Three quarters of American senators have declared they will not support foreign aid to the Palestinian Authority until the Obama administration completes a review of the Palestinians’ decision to unilaterally join the International Criminal Court (ICC).

The 75 senators wrote a letter to Secretary of State John Kerry saying that the move by PA President Mahmoud Abbas undermines the spirit of previous agreements between Israel and the Palestinians and harms prospects for peace. They also wrote about their concerns on Abbas’s aim to use the ICC as a venue to threaten Israel.

“President Abbas’ effort contravenes the spirit of earlier agreements between Israel and the Palestinian Authority and erodes the prospects for peace,” the senators wrote in a letter spearheaded by Sens. Marco Rubio (R-FL) and Kirsten Gillibrand (D-NY). “Therefore, the United States must make clear that joining the ICC is not a legitimate or viable path for the Palestinians.”

“The fact is that the only realistic and sustainable path to resolving the Israeli-Palestinian conflict is through direct negotiations between Israel and the Palestinians. For those negotiations to be successful, Israel needs a Palestinian partner that has renounced violence, refuses to partner with terrorists, accepts Israel’s right to exist as a Jewish state, and is willing to make compromises for peace. … President Abbas’s recent actions undermine these efforts and make a comprehensive peace agreement more difficult to achieve,” the senators added.
