Another one under the Obama bus. One lesson Obama has taught the world is to never rely on or trust the US. The Obama will turn on anyone in a minute if it is seen in Obama's interest of just if Zero is having a petty irritation.
You are absolutely correct. And this lack of trust will fall most heavily on America's allies. America's enemies will simply take advantage of the situation.
Russia is poised to take over the middle east, if they haven't already. China is likely to move on the Spratley's and Taiwan. North Korea is practicing nuclear blackmail and is digging silos for ICBMs. Once America signals that it won't enforce the Pax Americana, war will break out all over the world.
The next three years will be very interesting, and very dangerous.
