NATO leaders have convened in Ankara to deliberate on defense spending and alliance unity, amid ongoing tensions surrounding the U.S.-Israel military campaign against Iran. The summit, which aims to bolster European defense through significant arms deals, comes as former U.S. President Donald Trump publicly criticized several NATO allies for their lack of support in the ongoing conflict. Despite NATO’s official non-participation in the military campaign, the meeting underscores the fractious nature of transatlantic relations, particularly given Trump’s comments and NATO’s recent arms agreements.

The NATO discussions are set against the backdrop of Operation Epic Fury, a joint U.S.-Israel military offensive targeting Iran’s regime and nuclear capabilities. With NATO maintaining a non-combatant role, the organization has instead focused on logistical support and missile defense. Trump’s criticism of key European allies like Britain, France, and Germany reflects growing tensions as these nations have resisted offering their bases for U.S. military operations in Iran.

The pricing in prediction markets appears to reflect a decrease in the likelihood of U.S.-Iran diplomatic talks occurring by July 31, 2026. The probability has fallen from 72% to 57.5% within the past 24 hours, suggesting that the perceived lack of NATO unity and Trump’s public stance may be influencing expectations about the feasibility of diplomatic engagements between the U.S. and Iran.
