If Iran sinks a carrier then the us congress will declare an actual war and that will seal Irans fate. Also, seal the fate of hundreds of thousands of lives.
According to the Times of Israel Khamenei has been killed. I think that already counts as actual war.
I'm not so sure.
I think Trump would taco.
A carrier is fair game, especially when you shoot first.
There wouldn't be a coalition with half of Europe. Because of bridges burned.
So US citizens like you actually expect other countries to accept being attacked by you without as little as defending themselves?
