US Aid, Palestinian Wakaha

The Palestinians are now accusing the US of attempting to "blackmail" them by cutting the funds. According to the Palestinians, the US administration wants to force them to accept Trump's yet-to-be-unveiled plan for peace in the Middle East. It is worth noting, however, that the US administration has not yet presented its purported plan to the Palestinians or to any other party. So how can the US administration be trying to pressure or "blackmail" the Palestinians when no peace plan has ever been made public?
