Now we all know that the United States guaranteed the sovereignty of the Ukraine at the time we talked them into giving up their nukes. We also know that Obama is going to let Putin do what he wants despite the fact that he is in the same position as Hitler was in the Rhineland -- if anybody calls his bluff with credible military force he'll have to pull back because the modern portion of his so-called "revitalized" army is so few and thinly equipped that he can't afford to lose any state-of-the-art armored vehicles or aviation assets. We also know that if he were to get Russia involved in another Afghanistan he would be overthrown. So, what the Ukrainians need more than anything is credible deterrence in the form of Javelin anti-tank missiles and comparable MANPAD surface to air missles that are manufactured by us -- and the Israelis. Now Obama is not going to do that because it actually might work, and the Europeans are too scared of disrupting the supply of their natural gas, but there is no reason why the Israelis couldn't.
Think about it. The Israelis could strike back at the biggest supporter of Hezbollah and the Syrians using the hand of the Ukrainians. A post-Putin Russia would not be in a position or a mood to back the hand that threatens the Golan. Israeli backing of the Ukrainians would discredit the anti-Semite faction within Ukraine and Ukraine's Jews would become instantly popular overnight. Like Israel's quiet assistance to the Kurds, they become the friend of all the little countries fighting neighborhood bullies, strengthening their hand in the UN. The benefits would be so great that the Ukrainians wouldn't even have to pay the Israelis in anything other than energy credits redeemable at a later date.
One final thought that the Ukrainians might use to motivate the Europeans. As Frank Herbert noted in Dune, the power to destroy a thing is the power to control a thing. If they are sold out by the Euros, it would be the simplest of things to blow up those Russian pipelines that pass through their territory -- a place famous for using guerrilla warfare in causes good and bad over the centuries. Pipelines are, by their very nature, absolutely indefensible from such attacks. Sell us out, the Ukrainians can say, and we'll make sure you freeze your asses off next winter regardless. Power to the Fremen.
I ran these ideas past a graduate of the United States Military Academy at dinner the other night and he pronounced them sound, if risky. What have the Ukrainians, or the Israelis for that matter, got to lose?
