Dhimmi Carter blames America, again

In Jimmy Carter's latest article in the Guardian, he writes:

US objections have impeded Egyptian efforts to resolve differences between Hamas and Fatah that could lead to 2010 elections. With this stalemate, PLO leaders have decided that President Mahmoud Abbas will continue in power until elections can be held – a decision condemned by many Palestinians.

Abbas blames Iran for the breakdown in the negotiations - but Carter blames the US.

Just whose side is he on?
