Interestingly, he's Pro-Palestinian, and since Obama's pro-Israel, that could pose a problem if another situation happened in the Gaza.
Maybe my perspective is skewed by the personal feud between Obama and Netanyahu, but hasn't President Obama been one of the least friendly (or at least most skeptical) American President Israel has ever had to deal with since Dwight Eisenhower? He doesn't exactly strike me as a Zionist sympathizer.
I'm sure that if Netanyahu didn't act like a spoiled brat during the last four years then Obama's stance would have been indistinguishable from that of his predecessors.
