Yes, Germany should deal with it and drag us kicking and screaming into the mess. It would be sweet to see the AWACS at GK go into fighter escort role because they are ordered to, and let the fireworks begin. NATO includes the US and thus inseparable.
Poland was WARSAW Pact, as was the entire band of nations on Germany's and the EUs borders.
What is this NATO of which you speak?
NATO is a hollow farce, and has been for at least 20 years. There are two military powers in NATO, whose interests in this matter may be opposed to one anothers.
There is zero chance - ZERO - that "NATO" is going to have anything to do with this mess.
