Neutral on it myself. And for that matter, neutral on Israel in general. I'm perfectly aware there are arguments surrounding just about every single event that took place after WWII, and just about all of them are valid in some way. See, here's my problem: I wasn't born until long after Israel was created, so it's difficult for me to give my opinion on the subject. When I started paying attention, Israel was already a nation. If I were in charge of the whole thing, I'd probably try to find a way to get everyone to ignore the past and just focus on the situation, here and now, and try to find a way to get this generation to find the answer. It probably wouldn't work, but nothing seems to anyhow.
Actually, if you wanna go the "completely unexpected third opinion" route, the whole situation in the Middle East is the biggest argument I can think of against the idea of nationalism. After all, if there were no "nations" in the modern sense, and we found a different way to organize the political power centers in the region, there'd be no borders to fight over, would there?
Not saying that's the answer to the situation, but it's a fresh perspective nonetheless.
