While you are correct it wasn’t a war, but neither is this technically.

1/17/12: "@BarackObama will attack Iran in order to get re-elected."

9/16/13: "I predict that President Obama will at some point attack Iran in order save face!"

11/10/13: "Remember that I predicted a long time ago that President Obama will attack Iran because of his inability to negotiate properly - not skilled!"

"If Kamala wins, only death and destruction await because she is the candidate of endless wars. I am the candidate of peace. I am peace." - Presidential debate, 2024

If you voted for Trump, you voted precisely for this. Every accusation from him is either a confession in disguise or an unfulfilled wish.

Maybe Trump will claim the airstrikes were just a joke, like he does when he tells his supporters to use violence towards other Americans. Otherwise, the United States is definitely, unambiguously at war with Iran.
