Trump declared Iran will not get a nuclear weapon, claiming future historians will mark it as one of his administration's most critical achievements.

Three sharp counterpoints:

1. Iran wasn't actively building a nuke before this conflict escalated.

2. The Iran war may go down as America's Suez moment — the inflection point where U.S. global power started its decline.

3. This could be remembered as a self-inflicted wound: a president who torpedoed his own legacy by picking an avoidable war.
