Mr. Levy's article is somehwat simplistic and assumes a two-dimensional situation, which clearly isn't the case, save and except for Israel. After Oslo, the Gaza strip and the West Bank were treated similarly, yet the outcome vastly differed. This suggest that the outcome is also very much a factor of the willingness on the receiving end. In this respect, Lebanon, Gaza and the West Bank are driven by their own unique parameters and agendas. Rational consideration (like that of Mr. Levy) rarely applies, because the mindset differs. Israel only has two choices; safety and possibility of peace. In the West Bank the latter may be a front runner, but in Gaza, this just isn't the case. Until safety is a believable option, which it has never been, all other efforts are a waste of time. In fact, not using a military option, is probably undermining the chances of getting there.
