#MattYglesias makes an interesting point.
In the past, a two-state solution in Israel was undercut by Israeli security fears about a hostile, very intimate neighbor. But now, Yglesias argues, Israel and its Arab neighbors share a joint security interest in deterring Iran, but the Palestinian problem prevents full alliance and cooperation that would improve their mutual security. So security risks of a Palestinian state must be balanced against security benefits.
