Palestinians condemned as blackmail on Wednesday U.S. President Donald Trump’s threat to withhold future aid payments over what he called the Palestinians’ unwillingness to talk peace with Israel, Reuters reported.

Trump drew praise from a cabinet minister in Israeli Prime Minister Benjamin Netanyahu’s right-wing government but a warning from a former Israeli peace negotiator of the dangers in cutting off financial assistance to the Palestinians.

On Twitter on Tuesday, Trump said that Washington gives Palestinians “HUNDRED OF MILLIONS OF DOLLARS a year and get no appreciation or respect. They don’t even want to negotiate a long overdue peace treaty with Israel ... with the Palestinians no longer willing to talk peace, why should we make any of these massive future payments to them?”
