The international community and Israel have the same opinion regarding the Hamas government. We don't say we are going to boycott it forever. We say the Hamas government must abide by the obligations the Palestinian Authority has signed.
Foreign policy is all about a universe of bad decisions, imperfect decisions; every situation is different. The dynamics, the atmospherics, the people, the pressures, the geopolitical realities shift.
We don't want the Taliban to put down roots, or the al Qaeda to put down roots in Afghanistan that can facilitate Afghanistan becoming - once again - a launching pad for international terrorism.
