So, if Suleimani was invited to Iraq at the behest of the United States, under the guise that he was there to begin negotiations to de escalate tensions between the US and Iran, and the the US uses knowledge of that meeting to assassinate him, is that perfidy? It sounds a lot like perfidy.
Which is a war crime.
who's going to do a thing about it?
"Hey UN stop me with your Army. Oh Wait you got no Army!" -
Black Bush(as portrayed by Dave Chapelle) Donald Trump
Also if you think China or Russia will do
anything you're mistaken. Russia has seen Libya, Iraq etc. they know the US will fuck up at some point and they can swoop in and take the oil, same with the Chinese.
Chances of the US installing a stable new regime after OPERATION EAGLE CREAMPIE are next to zero.
Plus it really benefits their propaganda that they are the 'good' guys and the US the 'bad' guys. That has more value to both than any potential partnership with the sanctioned state of Iran ruled by Khamenei would have.
The only potential leader of a post-Khamenei military dictatorship of Iran was toasted by Trump at Baghdad Airport and the potential military coup before a war went out the window with him.
