Biden has proposed to remove Congressional oversight for arms transfers to Israel in the coming years. This is an extraordinary move to limit the powers of the legislature to monitor the actions of the Executive.
Secret deals aren't new for Biden, who arranged extensive covert networks for arms transfers to Ukraine. But now, he hopes to change the rules, ensuring total information security for the future, meaning we won't know about what is being sent to Israel like we did for Ukraine. This move has huge implications not just for the war, but for the legal ability of the US ruling class to covertly interfere in conflicts around the world.
The United States is terrified of public opposition to the war in Israel, and hopes to completely avoid a conversation on the issue of its secret business supporting them.
