billyboy, after hamas won the election in 06 IS/US imposed the embargo/sanctions, after that shalit was captured and then israel arrested and imprisoned 40 members of hamas, all from the palestinian legislative council. iow, they already tried your suggestion. maybe instead of imprisoning all those newly elected leaders they should have ended the blockade at that time. shalit wasn't captured in a vacum, he was captured after a brutal blockade was initiated and started to take effect. i believe the terms used in feb/06 was putting gaza on a 'diet' for democratically electing hamas.
