The mercans have been backing one side or another and running special forces interference in conflicts throughout the Middle East without "getting involved" since since some slitty eyed midgets blasted the shit out of them from their rice paddys in the 60's.
Did the Western media and governments not report 1300 fatalities from the chemical attack, but the aid agencies involved reported less than 300 casualties.
As far as the Iranians go, the mercans have been poking them with a big stick for a while as they need a war there to free the Iranian people (of their rights to any money from their Haliburton's* Oil Fields)
*or whomever are backing this administration.
As for the French, insignificant people are insignificant. Would you go to war alongside an country whose armed forces may go on strike at the merest hint of having to work 40 hours in a week... Fuck me the French Special Forces are called the French Foreign Legion for a reason.
Regardless of all this, what kind of idiot would actually start a war with their biggest customers. A WW3 kicking off between the Arab Nations, China and Russia V the West only serves two nations. It'd be like KFC and Burger King goading McDonalds into killing a shit load of fat people from council estates.
