President Donald Trump spoke with Israeli Prime Minister Benjamin Netanyahu to stop a planned wave of major strikes against Iran [1, 2].

The intervention marks a critical shift in the U.S. approach to the conflict, as it prevents a potential full-scale war between two regional powers following a fragile peace.

The phone call occurred earlier this month, hours after Israel and Iran exchanged fire for the first time since a U.S.-brokered truce in April 2026 [1, 2]. According to reports, the conversation led Netanyahu to cancel the planned military operation to avoid further escalation [2, 3].

An unnamed Israeli official said, "We were preparing for the biggest wave of strikes on Iran since the ceasefire took hold" [1]. The official said the scale of the planned attack was unprecedented since the truce had been established.

During the call, Trump said to the Israeli leader, "you better be very careful" [3]. Israeli officials said Trump told Netanyahu that Israel would be on its own if it chose to proceed with the strikes [2].

This warning regarding the lack of U.S. support reportedly prompted the decision to halt the operation [2]. The exchange between Washington and Jerusalem comes at a time of heightened volatility in the region, where the April truce had barely held before the recent exchange of fire [1, 2].

Netanyahu's decision to stand down reflects the significant influence the U.S. presidency maintains over Israeli military strategy, even when the U.S. threatens to withdraw its diplomatic or military backing.

This event underscores a transactional shift in U.S.-Israel relations. By conditioning support on restraint, the Trump administration is utilizing the threat of isolation to maintain regional stability and uphold the April 2026 truce, effectively limiting Israel's autonomy in its retaliatory strikes against Iran.
