US isn't the only deal in town...
EU are looking at it as well... They have different interests...
Could definitely see China having a look too..
At the end of the day, Russia's Military are pretty shit at the moment... EU might think this is their time to set a marker and put Russia in their place.. Next US President is probably going to side with Democracy unlike Trump...
Putin is a bully and if he isn't stopped, he is going to cause havoc... Letting him off the hook now allows him to maintain his reputation with his people and allow him to rearm for the next time. Ukraine drains him of both and if he loses, he isn't coming back for more..
