Except the issue you are claiming is happening has no evidence that it is actually occurring, there being 40,000 US troops in eastern europe (In case you are unaware, eastern europe is defined as everywhere east of the Ural river/mountains). While there are troops in Portugal, and all over Europe there is not 40,000 US troops in eastern Europe. This article
http://www.wsj.com/articles/pentagon...ope-1459324801 states there is only 60,000 in the entirety of Europe, with 4,200 being moved to the eastern lines. Or this article which says there is 5,000
http://sputniknews.com/europe/201606...ern-flank.html or
http://www.wsj.com/articles/closing-...sia-1466205268 which states "30,000 U.S., Polish and allied forces", which is the forces of NATO. So, if "your country" consists of
all of the following countries:
" Albania, Belgium, Bulgaria, Canada, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Turkey, United Kingdom, United States" then yes, there might be 40,000 combined forces for "your country". Here's another breakdown of the numbers

And, NATO is not in Eastern Europe for """training""", it is for a deterrent which should be obvious and is the real issue. If you look back in history, everyone has been somewhat scared of Russia in that area and after the recent Crimean conflict (Which, by the way, is one of several conflicts over this specific area involving Russia) even more could happen. Poland requested more troops from NATO because of Russia. Before World War 1, there was at least 3 revolutions where Poland tried to become their own country but Russia came and stomped the revolution each time. Otto Von Bismarck (Spearheaded the creation of Germany) was also afraid of Russia (He was really afraid of angering both France and Russia so tried to keep on good terms with at least one), Napoleon and Hitler both lost to Russia, etc. Stuff from World War 1 to present day I'm not as familiar with, however currently there is still quite some turmoil and Poland/other countries wants help in case something does happen, or show that they have help and deter Russia. The real issue is what is happening between Russia and the eastern European countries, not "oh geez, i heard this dumb rumor about my country doing something that's not actually happening and i gotta grab popcorn".
