There has been no peace process anyway. Just what have the Palestinians got to lose by the US refusing to accept Hamas as a legitimate player. The process by which the Palestinians achieve some measure of justice, including their own State based on the 67 lines with minor and mutually agreed land swaps, must now go through the UN. Because you know as certain as God made little green apples, if Fatah ditches Hamas, then the Israelis will hold the line that it is impossible to negotiate with Abbas only. Lets see it as a good thing that the US really no longer has a role except as an embarassing downright obliging backer of Israel.
