Only 3 minutes of thinking would have told me that with the pointless 10-year Iraq war over and the meaningless Afghan misadventure winding down, the US military-industrial complex needs a war somewhere to keep the weapons manufacturing contracts flowing and the Pentagon generals busy planning wars and promoting each other to the next level of general.
Of course American neo-cons like John McCain never needed anything more than a whiff of Soviet aggression or the rumor of human rights indignities somewhere we don't care about, to beat the drum of invasion.
Fortunately they have the Ukraine crisis now as a premise for arming another country against a bully aggressor. But should we be sending weapons to the Ukraine and escalating that situation? Russia will take the Ukraine if Putin wants to take it and any arms we ship over there will only prolong the battle and increase the loss of Ukrainian life, that is if direct US involvement doesn't actually precipitate a Russian invasion just to prove a point, where they wouldn't have invaded otherwise.
You can't argue, as some on Fox News have, that we insisted that the Ukraine abandon it's nuclear ambitions so we have a responsibility to protect her now. This was never going to be a nuclear contest so that argument isn't valid.
Obama is such an empty-suited joke on the international stage now that even the Europeans won't come on board with him to militarily defend the Ukraine if it comes to that. And the US alone sending weapons accomplishes nothing but to provoke Putin.
Unless Obama and the neo-cons in congress are willing to go toe-to-toe with Putin on the ground, which we aren't, we have no cards left to play in this except weak, trans-Atlantic rhetoric and laughable threats of pointless sanctions. Putin holds all the cards and all we can do is spectate.
