I'm not sure of your point. Because Germany and other western European countries have brought on their own demise through insane immigration and socialist policies, we must continue to defend them? Against what? - Russia? For what? - NATO?
Pres. Trump's reduction is a clear message to Germany and other NATO members to start pulling their own weight. Germany is one of the richest, if not the richest, nations in Europe. I vote pull even more out. They've been free-loading off us long enough while importing countless rapists, murderers, thieves, etc.
Also, why the Truman didn't make Germany, Italy, and Japan territories or protectorates is beyond me. Whatever happened to the "spoils of war"? Just think if they were US territories like Guam, Puerto Rico, Marianna Islands, Virgin Islands, Samoa, the incredible resources and power the US would have. Iraq/Aftganiscrap are the most recent. I'm tired of our children dying and being maimed for no damn reason other than promoting our ideals that they don't want.
Disclaimer: I am in no way an isolationist. I firmly believe we should stay engaged with allies, try to build more, and especially maintain our seat on the Security Council of the UN.
Our presence in Europe and elsewhere in the World is in our best interests. A military presence has proved to be a deterrence to conflict more often than the opposite. We are the most wealthy nation on the planet, in large part because we have been a trading nation since our beginning. Unlike most other countries, we have traded both raw materials and finished goods. Most countries can only do one or the other.
For years we relied on our control of the seas to support our trade advantage, but since WWII, air and land power have also become essential. That’s what happens when you are the big dog. Too ofter, politicians have been too quick to use our military power to achieve short term political aims, but that reflects poor political leadership, not a worldwide military presence. The U.S. Army fired it’s last shot on the soil of Western Europe on 8 May 1945. We should be thankful for those 75 years and resolve to ensure it lasts for another 75 years.
