Trump Faces "real and specific threats from Iran to assassinate him"

Iran has had a major grudge against Trump since he pulled the U.S. out of the multi-nation Iran nuclear deal and resumed economic sanctions in 2018.  When Itump ordered the assassination of  Iranian general Qassem Soleimani in 2020, that grudge became even more pressing.  Soleimani was head of the Islamic Revolutionary Guard Corps and widely regarded as the second most powerful man in Iran as well as a hero to many.

At the time, Iranian leaders vowed to take heavy revenge against the U.S.. but nothing much came of it.  They sure as hell haven't forgotten and will indeed try to assassinate Trump if they ever have the chance.  You can be sure the Iranians would rather have Kamala as president.  They have a better chance of getting Trump before he might be re-elected than after, so it's very possible he right now faces a credible death threat from Iran.
