1. LIEden's $6B $$ transfer to Iran is irrelevant, because it is far too recent to have resulted in Iran shipping arms to the Gaza Strip. The Arab Palis have been building (literally) their rockets arsenal and invasion tunnels for years, not a few weeks.
2. As moronic as the abandonment of US equipment in Afghanistan was, there are problems with the annoymorous claims that US arms are being used in Gaza:
* The thousands of rockets fired into Israel are of local, not US, manufacture
* The Arab Palis have used Soviet-era-design AKs for decades, which use different ammunition calibers than NATO-caliber arms; I would not accuse the Arab Palis of wisdom, but I think even they understand that mixing ammunition calibers will cause significant problems;
* There are problems with trying to ship arms from Afghanistan to the Gaza Strip; the first is that while shipping by sea is most efficient and has a chance to succeed, Afghanistan is land-locked; there are other barriers in between;
* While hatred of Jews borders on being Islamic doctrine, Afghanistan is not Arabic; Arab Muslims, Persian Muslims, and ______stan Muslims are tribal, not monolithic; Talibanders' foci for using the arms abandoned by LIEden are their own country and their ally-factions in neighboring countries (none of which are Arabic).
Much as I despise LIEden, the OP article's claim is clickbait absurdity.
