Napoleon and Hitler were arrogant enough to think they could conquer Russia. They found out the hard way. The U.S. should take heed. This country would never be able to fight a total, prolonged war against Russia. The United States from WWII doesn't exist anymore, nor does the military that liberated Europe.
It was the Canadian infantry that broke the backs. Either way, we were played by the same few controlling both sides. World wars were tragic when you look at the bigger picture.
