Contrived US/Russia “tensions” benefit the Warfare State

Pentagon is sending troops and war gear to the border of Russia, the first such deployment since the end of the Cold War.  The deployment is called the, “European Reassurance Initiative“, and is clearly meant to provoke Russia into a first strike.  So, around 4,200 troops are going to six countries: Lithuania, Estonia, Latvia, Poland, Romania, and Bulgaria, along with hundreds of tanks and other gear.  How would we feel if Russia lined the border between the US and Canada with Russian troops and Russian nukes?
