The world should give thanks that the greatest military in history is in the United States. Imagine if you will this military force in Russia, in China, in Iran, in North Korea or in most any other country. Nationalism always lurks beneath the surface in these other countries and history shows it doesn't take much to fuel the desire for more territory. Would other countries follow the example of the US after WW 2 where instead of vanquishing the enemy the victor helped to rebuild the enemy. The United States is unique in many ways and one of the more important is a population drawn from all parts of the globe. Recall President Reagan when he said you can move to France but you will never be a Frenchman or you can move to Germany but you will never be a German but you can move to America and you can be an American.
