Trump had no intention of honoring it. Trump signed it to buy time and steal from Peter to pay Paul when it comes to missiles. taking supplies from other theaters and to make more money on the stock market. Trump gives a SFA for economies of the US and her Allies.
The US will not win this war because they have no strategy. They put a former Fox News employee as chief of defense. Yep Hegseth. Seriously qualified for the job? Umm no. And Trump and his MAGA rodeo clowns got rid of all the competent leadership in both the military and intelligence agencies.
A lot of the advisors are gone, which is why is his second term is worse than his first term.
No Trump wasn't going to honor the MOU, but with a signature I imagine that means Iran does not have honor it either. They basically have Trump by the balls. About all Trump can do now is use force. Israel isn't gonna step down till things get even worse. The UAE etc would have to step in and force them out.
