The world has changed. We are now energy independent. NATO has been a sham for decades disguising the fact that all of its members lean far too heavily on the US. Our "allies" have become spoiled children expecting us to tolerate one way trade, and intervention into our internal affairs. It's time to leave Europe and the middle east to resolve their own issues. Not one more of our soldiers lives, limbs or one more dollar should be squandered to enrich European oligarchs. We have had enough.
