President Donald Trump said the United States could launch new military attacks against Iran after a provisional cease-fire agreement ends [1].

The statements signal a precarious peace in the Middle East, as the U.S. executive branch and Congress clash over the legal authority to conduct airstrikes. This tension threatens to undermine the stability of the current diplomatic truce.

On June 17, 2026, the U.S. and Iran signed a provisional cease-fire agreement [1]. However, Trump has since indicated that the truce is temporary and that the U.S. must maintain pressure on Tehran. In a statement reported on June 17, Trump said, "The United States will not accept that Iran continues with its aggressions; we are ready for new bombings" [1].

Reports on the location of these remarks vary. Some sources place the comments at a NATO summit in Turkey, while others attribute them to high-level negotiations in Switzerland [2, 3]. Despite the differing locations, the message remained consistent: the U.S. remains prepared for military action.

On June 23, Trump said the U.S. could resume attacks against Iran "even tonight if necessary" [4].

This stance has led to a confrontation with the U.S. Senate. On June 24, 2026, the Senate reached a decision requiring congressional approval before any new attacks against Iran can be launched [5]. This resolution was supported by four Republican senators who joined Democrats to pass the measure [6].

Trump responded to the legislative restriction by criticizing the lawmakers involved. "These senators are getting in the way of the U.S. work by requiring Congressional authorization for any attack on Iran," Trump said [5].

While some reports suggest the cease-fire is ending, other sources indicate the agreement remains in place as the two nations navigate these diplomatic and legislative hurdles [1, 7].

“"The United States will not accept that Iran continues with its aggressions; we are ready for new bombings."”

The conflict between the White House and the Senate represents a significant constitutional struggle over war powers. By requiring congressional approval for strikes, the Senate is attempting to curb unilateral executive action in the Middle East. This internal U.S. division may be perceived by Iran as a weakness or a strategic window, potentially complicating the longevity of the June 17 cease-fire.
