On March 25, 2025, Israeli aircraft struck a set of Syrian airfields. The targets were not Syrian assets, instead they were the sites Turkey had surveyed for planned forward military bases. Ankara quietly shelved the deployment.

That is what the Israel-Turkey rivalry looks like when it is working as designed: a NATO member and a US major non-NATO ally maneuvering against each other in a third country, close enough to require a deconfliction hotline, disciplined enough that neither has yet acknowledged the confrontation for what it is. The two governments have run a channel through Azerbaijani mediation to prevent accidents. Turkish officials describe it as, "strictly technical," signaling neither normalization nor any convergence.

The conditions that made the channel necessary are getting worse, and the outside power that has historically kept this rivalry from becoming a rupture is changing.

Trump's Gift to Erdogan

When Donald Trump landed in Ankara on July 7, 2026 for the NATO summit he became the first sitting US president to visit Turkey in over a decade. He arrived with what aides openly called a "gift bag" for President Recep Tayyip Erdogan. On CAATSA sanctions, imposed in 2020 over Turkey's purchase of Russia's S-400 system, Trump was categorical: "We're going to be taking the sanctions off; it's time. We don't want to sanction friends." On F110 engines for Turkey's homegrown KAAN fighter, the administration notified key lawmakers it was proceeding. The F-35 remained genuinely conditional, something his administration would "certainly consider." Erdogan told reporters Trump had pledged six aircraft and “always keeps his word”.

Standing beside Erdogan, Trump said Turkey had proven a more loyal partner than some allies Washington once counted on.

Israel's reaction was immediate and unprecedented. Speaking to Fox News and CNN, Prime Minister Benjamin Netanyahu warned that arming Turkey with F-35s would upset the regional balance. He described Erdogan's government as ideologically hostile to Washington and openly threatening to Israel, and pointed to Turkey's continued presence in northern Cyprus. It was the first time Israel had publicly opposed a US arms sale to a fellow NATO member.

Trump was reportedly irritated. Netanyahu insisted the two governments still saw eye-to-eye on the big picture. This difference is worth noting.

They do not see eye-to-eye, and the reason is not sentiment. This administration's Middle East policy seems focused on commercial and strategic arithmetic. On that scale Turkey scores well: 85 million people, a NATO air force, a fast-growing arms industry, control of the Bosporus, and a leader willing to transact. Israel's ability to shape US decisions in the region has always rested on an unstated premise: Washington values the relationship with Israel above the deal in front of it. Ankara is testing that premise. So far, Washington is not objecting.

The pattern repeated within three weeks. On July 8, the State Department initiated the rescission of Syria's designation as a state sponsor of terrorism, a status in place since 1979, following Trump's meeting with Syrian President Ahmed al-Sharaa. On July 22, Washington and Riyadh announced a nuclear cooperation agreement. Neither move was calibrated to Israeli preferences, but to American interests.

What Turkey Gained While Israel Was Fighting

Ankara's leverage did not appear in July. It accumulated while Israel was occupied elsewhere.

Syria is the clearest case. Since Bashar al-Assad's fall in December 2024, Turkey has established itself as the dominant external patron of al-Sharaa's government. On July 19, 2026, al-Sharaa consolidated the security apparatus under Interior Minister Anas Khattab, who now also heads the National Security Bureau, with Abdul Qader Tahan installed at General Intelligence and Hussein al-Salamah as Khattab's deputy. For Turkey, a centralized Damascus under a friendly government is a forward base, a reconstruction market, and a check on Kurdish autonomy along its southern border all at once.

Israel reads the same arrangement as a threat under construction, and has acted accordingly. In the seven months after Assad fell, Israel conducted roughly 988 air and artillery strikes in Syria, nearly triple its previous rate, including against the Presidential Palace and Ministry of Defense in Damascus. The March 2025 framework for integrating Kurdish forces into the Syrian state remains frozen, which Turkish officials blame largely on Israeli operations destabilizing the Syrian government.

Beyond the Levant, Turkey's footprint keeps widening. In Somalia it operates its largest overseas military base, has trained more than 15,000 soldiers, deployed F-16s and armor, and in 2026 began offshore oil drilling protected by Turkish naval assets. These are moves aimed in part at countering Israel's outreach to Somaliland. Turkey's defense minister says other African governments are now requesting the same security-and-investment package. Layered onto bases in Qatar and northern Iraq, Ankara has assembled a chain of footholds from the Horn of Africa to the Caucasus.

Two structural shifts accelerated this. Iran's regional network was degraded by the 2026 war, leaving a vacuum in Syria and Lebanon that Turkish diplomacy, trade, and reconstruction capital are filling faster than anyone else. Iran is not finished, and Russia was preparing Su-35 deliveries to Tehran the same week Trump was in Ankara.

Meanwhile Moscow's grip on the South Caucasus eroded after the 2020 Nagorno-Karabakh war, when most of its forces was deployed in the Ukrainian war, and after the US brokered the 2025 Armenia-Azerbaijan framework, which opened the Zangezur corridor linking Azerbaijan to Turkey.

Israel forging new alliances

Israel has also been forging alliances, no longer counting on the US as their sole guarantee.

In December 2025, Israel, Greece, and Cyprus held their tenth trilateral summit in Jerusalem, where Netanyahu spoke against those who dream of restoring old empires. The three signed a 2026 military cooperation plan covering joint air and naval exercises, intelligence sharing, and reported discussions of a roughly 2,500-strong rapid-deployment force. By February 2026, Netanyahu was describing a broader "hexagon of alliances" built around Greece, Cyprus, and India.

Ankara's counter-positioning is equally deliberate. Turkey has hosted Hamas officials for years and holds real influence over any postwar settlement in Gaza. Foreign Minister Hakan Fidan's remark that Israel had become a burden humanity could no longer bear drew an Israeli rebuke as incitement. Each government now treats the other's regional relationships as evidence of intent.

Where It Breaks

Direct confrontation remains unlikely, but not impossible. Both capitals understand the costs. But the deconfliction channel is a technical fix for a strategic problem, and four scenarios handled incorrectly could force the two powers into collision.

Syria is the live one. Israeli strikes to prevent hostile entrenchment collide directly with Turkey's project of a unified, centrally governed Syrian state. Israel has already struck sites Turkey intended to occupy. Repeat that once with Turkish personnel present and the hotline becomes a record of a failure rather than a mechanism preventing one.

Lebanon compounds it: Hezbollah degraded but intact, Turkey's expanding humanitarian and political footprint, and continued Israeli operations against Hezbollah infrastructure pulling outside patrons into direct rivalry. Trump is suggesting that Syria should intervene, something Israel can not accept.

Cyprus, divided since 1974, is where Israeli-Greek-Cypriot military integration and a prospective joint rapid-reaction force meet Turkish assertiveness in the Eastern Mediterranean. While several of the nations are NATO members, new hostility risks drawing in allied nations.

The F-35 decision itself is the fourth. If Congress and the Pentagon proceed over Israeli objections, it is a tangible erosion of the qualitative military edge that Netanyahu argues is the foundation of deterrence.

Conclusion

Israel and Turkey have been rivals for a decade; and for most of that decade, the fault line stayed closed because the US had an interest in keeping it closed. But the Ankara summit demonstrated, reinforced by the Syria delisting and the Saudi nuclear agreement, that this administration will price each decision on its own merits without allowing allies to veto them. That is a coherent policy. But it risks removing the pressure that has been holding two armed, ambitious, US-aligned states apart in the same contested space.

Washington is not choosing between Israel and Turkey. It is counting on the two allies staying away from an armed conflict. The question is whether a deconfliction hotline routed through Baku can carry the weight that American guarantees used to.

The Iranian leadership appears to be intent on demonstrating its defiance and courage in the face of American force while also humiliating the “most powerful man in the world.”

“Counting Coup, or striking an enemy, was the highest honor earned by warriors participating in the intertribal wars of the Great Plains. Key to a man’s success in Plains combat was demonstrating his own courage by proving superiority over his opponent and, in a competitive sense, over his own comrades.

Killing was a part of war, but showing courage in the process was more important for individual status. This was best accomplished by risking one’s life in charging the enemy on foot or horseback to get close enough to touch or strike him with the hand, a weapon, or a “coupstick.”

Humiliating the enemy also played a part in this fighting…

Counting Coup, then, was the epitome of a type of warfare that pitted skill and daring of one man against another.”

Walking the Line

Iran is playing a very dangerous game. In the face of the awesome military power of the United States, in between desultory negotiating sessions, they continue to touch the enemy by launching attacks against U.S. and allied Gulf facilities. Recently, they have reached farther afield, striking U.S. assets in an Egyptian port. This would seem to be inexplicable behavior, given the U.S.’s obvious desire for a deal, inviting as it has strong retaliatory strikes against Iran’s increasingly beleaguered military, and potentially civilian, infrastructure. Most recently, we are seeing reports of possible Iranian cyberattacks on the water supplies of U.S. cities; such activities are certain to continue and likely to escalate, plausibly deniable and effective in sowing fear as they are. The question is why?

It may be simple hubris. It may be a misread of the desperation of their opponent. Or simply overconfidence in the strength of their position. It most certainly is part and parcel of a purposeful negotiating strategy, a reminder to all involved that Iranian forces can reach out and touch you whenever they wish.

Regardless, they are walking a fine line, and they have placed this conflict squarely in the crosshairs of unintended consequences.

As they so often do, they risk overreaching. Should one of these missile or drone strikes make it through, whether by luck or skill, and inflict truly significant casualties on U.S. personnel, either in a land-based facility or on a naval vessel for example, this could surge American support for a massive response, possibly including – however unlikely – ground troops, radically altering and escalating the course of this conflict.

Internal Factions at Play

The Iranian leadership’s actions, however, are likely aimed not only at the United States but may be the result of continued factional maneuvering in Tehran, as groups jockey for advantage for what comes next. Now that it appears likely the regime will survive, they are no doubt looking ahead to where they will land in a new regime. As both factions and individuals.

As I wrote in ‘Is Iran Controlling the Gulf Conflict?’: “I would posit that the newly ascended Supreme Leader, Mojtaba Khamenei, may in fact be a phantom leader. Alive in some fashion, perhaps largely incapacitated, but not actually in charge. And even if able to coherently express his views, in no way nearly as powerful or influential as his father. The seemingly reckless actions of the regime in courting U.S. retaliation may in actuality reflect a lack of a coherent decision-making process as opposed to a unified one. I think it is quite possible that competing factions within the regime are using Mojtaba as an avatar while they maneuver for decisive advantage.”

Get Out!

On 15 May, I laid out in “Ground Hog Day”, a recommended way forward for the U.S. that I think largely still applies. It is a measure of how fruitless continued military action is that these remain relevant today:

“Make a deal with Iran. One that they will accept. This will require painful concessions and is certain to include provisions that many will find objectionable, including significant sanctions relief. And it will leave the Iranian regime in place and in control of Iran. For now.”

“As much as I would prefer to see regime change in Iran, I believe a deal may be the only realistic way out of the Groundhog Day-like doom loop in which we find ourselves. Simply put, the administration squandered the initial opportunity presented by a unique confluence of events by its lack of strategic planning and a fundamental misunderstanding of Iran and the Iranian regime.”

“As a result, we are going to have to step back and take a longer view. I pity the people of Iran, at least in the near term. They are certain to suffer the brunt of the regime’s immediate ire. That is a hard truth.”

“This is not, however, the end of the story. Iran’s internal weaknesses still matter–and may shape what comes next more than battlefield successes. I am cautiously, very cautiously optimistic that even barring regime change, Iran’s leadership will be forced to change direction.”

“The issues facing Iran prior to the War were serious, in fact existential – a collapsing economy, hyper-inflation, severe water shortages, lack of electricity, and growing widespread popular anger and unrest – and are ongoing and only getting worse. Whatever the Iranian leadership looks like, it will have to address these issues. And it is not clear that they will be capable of doing this without outside help. This is where the U.S. and hopefully our Western allies come in: sanctions relief, and extensive economic and other assistance in exchange for real changes in policy and a pullback on objectionable activities and programs. The potential for this may, and I say may, have increased with the removal of Ali Khamenei from the Supreme Leader’s seat. But it will depend on whether his son and successor, Mojtaba, is less rigidly ideological than his father. We will see if he is willing to put the Iranian people ahead of the regime.”

What Awaits!

It is becoming more obvious by the day that the U.S. needs to come to a negotiated settlement with Iran. And the terms of this settlement are certain to be painful and unsatisfactory from the perspective of the West. But continuing tit-for-tat airstrikes simply prolongs the pain and risks horrific unintended consequences without solving the problem, as well as providing the regime with a distraction from its appalling management of Iran’s economy, natural resources, and foreign policy.
