also with us, is nura, a palestinian human rights attorney. thank you both of you for being here.aron, you have a fascinating piece on foreign policy where you say that the u.s. should stay out of this conflict, at least for now. you write, there's a real danger that u.s. credibility, already badly undermined by the failure of kerry's efforts so far, could be harmed even more by yet another failed attempt at making peace. >> first of all, this is going to be a cruel and unforgiving humanitarian situation, largely for palestinians. although if hamas does make good on its threats to launch high trajectory weapons into densely populated weapons like tel aviv, it could literally change the game, but the reality is we have seen this movie twice before between israel and hamas. once in 2008 and 2009. israelis spend two weeks including a significant ground incursion, did a lot of damage, maybe some deterrence, but failed essentially to stop the acquisition of high trajectory weapons. they tried again in 2012. this time, the operation lasted a week. no ground incursion. limited air strike
