Israel captured these lands filled with hostiles. We can't hold it for them. They will have to either cut a demarcation line west from the top of the Dead Sea to Jerusalem and push every Palestinian in to it, then build a wall, or kill 'em all. But don't hold your breath for the Palestinians to stop being . . . Palestinians. Israel should have tried harder to get along with them instead of kicking them off their land and building settlements, but that's water under the bridge now. They've now got full bore generational hatred cooking and it's boiling up into a sporadic civil war. But under no circumstances should American troops be considered in that mess. In fact, if Israel is caught spying on us, we should withold all donations. They are a dependant, not an ally.
Israel has every right to do what they think is right in defense of their own interests, and if that means they decide to engage in a full tilt war with Palestine then I will support their right to do so.
However, I don't support our continuing to give them (or anyone else) billions of dollars in aid every year. Israel is a nuclear power, they have hundreds of atomic weapons, and they are also a technological powerhouse. Some of the finest engineers I have ever worked with have been Jews, some of them from Israel, and the notion that a nation composed of such talented and energetic people needs our financial and military aid seems absurd on the face of it.
We can be friends with Israel, and sell them arms and trade with them, but let us not be joined at the hip with them, let us allow them to stand on their own two feet and fight their own battles. Again, they have over two hundred atomic weapons. Have you seen what their pilots do to our pilots in war games? I don't think anybody is going to be driving them into the ocean anytime soon. Let them look out for their own interests on their own terms, and let us do the same.
