The prisoner swap is historic, hopeful and important. This is an excellent opportunity to consolidate real gains. The Israeli government must acknowledge that Hamas is a legitimate and constructive negotiating partner with an intrinsic role to play in larger negotiations. Hamas must also recognize that Israel has done a humane and productive thing and is a partner, not obstacle in the future of our region. It's easy to grab the thing that had been taken from you and scowl at the person who took it, and people on both sides will do that, but we must also celebrate that it took a change of heart - and one in the right direction - on both sides to achieve this agreement. Now hug and make up.
