In February 2006, Quartet envoy James Wolfensohn warned that the Palestinian Authority was on the verge of economic collapse within two weeks time, because of the cessation of tax funds to the PA from Israel. In a letter to the US government, Wolfensohn warned that the economic situation could lead to violence. In his report of May 2006, Wolfensohn questioned the decision of Western powers to cut all but humanitarian aid to the Palestinians' Hamas-led government. He recalled that $1.3 billion a year was spent on assistance to the Palestinians and asked: "Will we now simply abandon these goals?"
