The US and Israel are considering how to destabilize the new Palestinian government. Because we believe in democracy so much.
Of course the US and Israel have the right to refuse to trade with hostile nations. Of course Hamas should recognize Israel, renounce violence, etc. I'll go father, even: if the Palestinians had embraced nonviolence at the outset, they would have their own stable and prosperous nation by now, within the 1967 borders, with East Jerusalem as its capitol.
But to refuse to negotiate with the elected leaders of your enemies is to refuse to negotiate in good faith. The Palestinians have said that they feel that Hamas is the best honest broker of their interests. And really, given the corruption of Fatah and the PA, who can blame them? Hamas has been taking care of their own people: running schools, taking care of the elderly, finding people jobs. Is it any wonder that they are recognized as leaders?
By refusing to recognize the will of the Palestinians, the US and Israel are effectively saying: “You are not people. We do not have to take you or your desires seriously.” This makes peace negotiations impossible.
Ok, I haven't written my page today. I need to get to work.
