I was always under the impression that Israel was a Jewish State and not a vassal state of the UN, the EU, or the USA. Biden will be gone but the Jews of Israel will continue to have to deal with Arab terror. So they either commit suicide or downgrade ties with the USA and stop accepting the $3.8 Billion and produce their own weapons and ammunition. Until this can be accomplished then produce and use dumb cheap ammunition and advise Biden that any additional kills are on him. Tell him that along with the $3.8 billion he can keep his advice to himself. Russia and China have no interest in attacking Israel on behalf of the Arabs.
We did quite well in 1948,1956 and 1967 without American help even though Eisenhower threatened to bomb Israel if they did not withdraw from the Sinai in 1956. It would not be in the US interest to alienate a regional power as Israel. Russia and China would jump at the chance to replace them.
