Congress has a process where the executive branch notifies lawmakers before certain weapons sales to other countries go through, giving Congress a chance to object. This resolution is that objection: it would block a specific planned sale of U.S. weapons and military equipment to Israel's government. If passed, the sale would not go forward as proposed; if it fails, the sale could proceed as normal. The bill itself doesn't say what the weapons are, why the sale was proposed, or what happens after — just that this particular deal would be stopped if Congress votes to disapprove it.
