Among those at the meeting were representatives from Germany, France, the UK, Italy, Egypt, Jordan, Saudi Arabia, Turkey, Morocco and Brazil, along with several intergovernmental organizations.
However, only a fraction of the nations represented at the Madrid Group meeting actually supply Israel with armaments.
Israel is also one of the world’s top exporters of armaments, so it has a powerful internal supply of weaponry as well.
Crucially, three nations account for almost all of Israel’s weapons supply: the United States, Germany and Italy.
I don’t see any such action occurring now or in the future from the US.
