A group of influential Republican senators has sent a letter to International Criminal Court (ICC) chief prosecutor Karim Khan, warning him not to issue international arrest warrants against Israeli Prime Minister Benjamin Netanyahu and other Israeli officials, and threatening him with “severe sanctions” if he does so.

In a terse, one-page letter obtained exclusively by Zeteo, and signed by 12 GOP senators, including Tom Cotton of Arkansas, Florida’s Marco Rubio, and Ted Cruz of Texas, Khan is informed that any attempt by the ICC to hold Netanyahu and his colleagues to account for their actions in Gaza will be interpreted “not only as a threat to Israel’s sovereignty but to the sovereignty of the United States.”

“Target Israel and we will target you,” the senators tell Khan, adding that they will “sanction your employees and associates, and bar you and your families from the United States.”

In their letter, the dozen Republican senators remind Khan that the U.S. “demonstrated in the American Service-Members’ Protection Act the lengths to which we will go to protect [its] sovereignty.”

The ASPA, signed into law by George W. Bush in 2002, has since become widely known as “The Hague Invasion Act” because it authorizes the U.S. president “to use all means necessary and appropriate” to bring about the release not just of U.S. persons but also allies who are imprisoned or detained by the ICC.
