All U.S. aid to Israel has been cut off, including any sort of military or financial deals. All Israeli nationals in the United States have been ordered to leave the country in 24 hours.
Reasons are currently unknown as to why the United States has decided to cut off their greatest ally from American aid.
There are speculations that Israel will imminently conduct their own military strikes against Iran without American approval in the middle of diplomatic talks between Iran and the United States. Such attacks will cause these talks to fall and may cause Iran to shut off any sort of diplomacy with the United States. Trump deciding to cut off Israel may be a signal to Iran that they are not responsible for what is about to happen next.
This comes after Iran posted a video of a U.S. aircraft carrier being in the crosshairs of an Iranian drone.
