For me it's clear that the so called European army will not be peaceful. NATO is more than enough to save guard European borders. A better integration of European solider under us commands seems to be the most cost effective and efficient way to achieve killing domination. No nations combined can fight NATO, and or even more the US against the world wins in all scenario. If life exists is to be free to expand not to centralize and collapse. The values of Liberty embedded in the foundation of the USA stand Obama... What else can you throw at it low information/intellect oligarchs?
Nato is more than enough but don't be mistaken that the usa can take on the whole world. Thats not something that would ever happen but russia alone is enough trouble for usa, never mind throwing in chin, korea and a few European countries. soon enough Chinas going to knock America down a notch in the list of super power.
