America is currently on a path to destruction. With Obama and a RAT super-majority in the Congress, it will be full speed ahead.

At the risk of some fool invoking Godwin's Law....when the Wehrmacht invaded Yugoslavia, the takeover was quick. Over the course of the next 3 years, more and more manpower and resources were required to protect the supply lines into Greece and the Eastern front (short article here: Yugoslavia During WWII )
