The US and Russia both profit off of Iran in their own way. The US has the GCC member countries scared ****less burning cash on arms, jets and armour out the wazoo. They've been big customers especially this past decade. Russia has Iran buying Russian arms in response. And Russia is one of the few who is willing to sell to them and their proxies. They've got a nice racket going. The thing to never forget is that no matter who kills each other, the military-industrial complex is always the winner.
