The voluntary nature of UNRWA funding has led to budgetary problems due to acute emergencies or political developments in donor countries. In 2009, officials spoke of a "dire financial crisis", including a funding shortfall of $200 million, in the wake of the Israeli offensive in Gaza In August 2018, the U.S. ceased its contributions, arguing that UNRWA's mandate should be reduced to the few hundred thousand Palestinians alive when the agency was created. The U.S. decision resulted in the loss of $300 million out of the $1.2 billion budget, contributing to an overall deficit of $446 million. The shortfall was covered with increased contributions from elsewhere.
