THE USA had to vote against observer status, otherwise it would have weakened Abbas' victory in the eyes of Gazan's and pro-Hamas palestinians. Palestinian victory was a shoe-in, the question is who will rule Palestine. The Muslim's Brotherhoods proxy or the USA's proxy. By the USA opposing Abbas, it give Abbas greater street creeds in Palestine. Israel, actually would prefer Hamas. It would justify continuing the occupation and the settlement industry in the West Bank. A peaceful Pro USA Palestine is Israel's colonial enemy. Israel needs an extremist Palestine in order to pursue its own extremist goals.
