So just 3 days before the killing of Soleimani the Iran, Russia, and China alliance had just wrapped up Maritime war drills sending a threat to the US. Trust me the US and its allies does not want to get into a war with the Russia, China, Iran, and North Korea alliance + ISIS. There's no way the West with its alliance can win such a war...no wonder Trump is sucking the dirt off Putin's balls.
Check out this Russian warship harassing a US Naval Destroyer. This is one time I kinda would liked to have seen the US send Russia a message and sank that ship. But we all know Trump can't resist the taste of Putin nuts.
