The United States on Monday will adopt an aggressive posture against the International Criminal Court (ICC) in The Hague, threatening sanctions against its judges if they proceed with an investigation into alleged war crimes committed by Americans in Afghanistan.

President Donald Trump's national security adviser, John Bolton, is to make the announcement in a midday speech to the Federalist Society, a conservative group, in Washington. It will be his first major address since joining the Trump White House.

"The United States will use any means necessary to protect our citizens and those of our allies from unjust prosecution by this illegitimate court," Bolton will say, according to a draft of his speech seen by Reuters.

Bolton will also say that the State Department will announce the closure of the Palestine Liberation Organization (PLO) office in Washington out of concern about Palestinian attempts to prompt an ICC investigation of Israel.

The PLO office in Washington did not immediately respond to a request for comment.

"The United States will always stand with our friend and ally, Israel," says Bolton's draft text.
