Iran conflict escalates beyond Trump's control with no clear end

Three weeks into the conflict with Iran, the situation has escalated beyond what Donald Trump can control. The war has not produced the decisive defeat Trump had expected, and there is no clear end in sight.

Analysts say Iran is now exploiting weaknesses in the U.S. position and appears more empowered than before the fighting started. Trump has resorted to making threats again, while experts are discussing how the war might end and what the worst possible scenarios could be.
