I'd agree with all of that and still Eastern Europe is falling over themselves to get into NATO. Ask yourself why? What is it about Russia (and Putin) that has them running away into the bosom of the big bad USA? You're full of justifications for Russian transgressions but unable to see the simple fact that nobody outside of Iran and a few puppet states want to be their ally. I'm not even making the case that America is noble. We've done some evil **** but still we are more noble than Russia, especially given our relative power supremacy.
It's not just that Eastern European countries are running away from Russia into the bosom of the USA. The USA is also pouring its influence into Europe to gain cooperation. Keep in perspective the USA is dominant in controlling financial resources (IMF, World Bank, etc.) and can pressure/bribe governments globally to do as the US wishes. There are only three countries in the MIddle East for instance, that do not have US military bases on their soil. Those countries are Iran, Syria, and I believe Lebanon. Guess which countries are under attack - if not militarily, then financially - by the United States.
But aside from who is the more good and who is the more bad, Russia or the US, the overriding question that I'm concerned with, is what policy makes the best sense for myself and the United States citizenry? What is best for the typical US citizen doesn't necessarily align with the policy objectives of the US government (despite the fact that the Congress and President are elected), the Pentagon, the multi-national corporations, and the media which happens to be dominated by those factions listed. Excuse me, but I don't believe securing Eastern Europe is a national security threat worth risking a direct military confrontation with a nuclear power.
There's no question American is historically noble, but in my opinion the America of today does not remotely resemble the American we hold nostalgic. For Pete's sake, of the two leading Presidential candidates, one allegedly did quite a bit of business through mafia ties, and the other is a treasonous liar who has a multi-billion dollar slush fund called the Clinton foundation. And the typical American response to that is to say Putin is Hitler.
