Donald Trump is the lowest of low IQ Presidents in my lifetime. It showed up bigtime when he went to war with Iran. He di not ask any decent questions and ignored some advice. see Tom Nicholls.
The 'short' war blew up in his face ( pun intended). The USA wasted for example patriot missiles against Iran. Those missiles did not help in subduing Iran at all. the USA again showed it is poor against asymmetric warfare . This should not be a surprise. the white house still believes russia is winning well against Ukraine ( who need patriot missiles now).
Given an airforce is unlikely to win a war and it didn't even given Iran's decrepit defences then taking control of the strait of hormuz and therefore hiking up petrol prices was always going to hurt Trump politically more so in a mid-term year.
Thus any threats from Trump towards Iran are hollow and Iran knows it. Unlike trump they neither have to worry about their citizen's plight nor care.
Any further increases in 'war' will lead to a rise in petrol prices and thus hurt Trump. Trump know this , Iran knows this add to this how unpopular the war is and y
You can see how trump is kidding himself.
