Putin knows what he is doing , crazy is not one of his problems …………..everything is calculated , and done for a reason . We do it all the time when we want to make a point , lest we forget ……………The US is NATO when you get down to it , the others contribution has never been nearly what ours has been in conflicts . I dont think NATO is really all that cohesive anymore , considering all the BS conflicts we have dragged others into in the middle east for such a long period of time . That and the fact that the Europeans have their own financial problems looming like we do . Not sure if push came to shove in a hard way , that the Europeans would be willing to risk the substantial consequences of war over Ukraine . Its one thing for us to go someplace else and fight , but its another to have war on your own soil . These drills are just part of the chess game , Putin is showing monkey man that he is not afraid of him . Its still early , and the longer it drags out , the stronger the Russian position will be , if they hang onto the Crimea , they have already won . Which seems likely that they will .
