The U.S. is reportedly threatening to veto a United Nations Security Council resolution aimed at preventing the use of rape and sexual violence as a weapon of war and terrorism. The issue at hand? The proposal includes promises to provide reproductive and sexual health support to survivors of rape in conflict — and the U.S. is allegedly having none of it.

Germany, the current president of the Security Council, proposed the draft resolution, which is slated to be discussed in New York on Tuesday. As German foreign minister Heiko Maas and actress-activist Angelina Jolie explained in a Washington Post op-ed, the resolution seeks to punish perpetrators of sexual violence in conflict, improve the monitoring of such violence and boost support for the survivors of these atrocities.

According to The Guardian, the U.S. has already succeeded in hobbling the resolution after it — together with Russia and China — opposed a clause that promised the creation of a new monitoring body that would have tracked and reported such crimes.

The formal monitoring mechanism was removed from the resolution, The Guardian reported, but the American delegation’s veto threat has not been withdrawn.

“We are not even sure whether we are having the resolution tomorrow, because of the threats of a veto from the U.S.,” Pramila Patten, the U.N. special representative on sexual violence in conflict, told the British paper on Monday.

According to Patten, the U.S. is unhappy with language in the resolution that refers to the provision of “comprehensive healthcare services including sexual and reproductive health” to rape survivors.

This language has been interpreted by the U.S. as a reference to abortion, CNN reported. A U.N. source told the network that this is a “red line” for the U.S. ― which, under the Trump administration, has been pushing an anti-abortion agenda both at home and abroad.
