I think the latter is entirely unnecessary. The US and its co-sponsor lackeys could do plenty by simply withdrawing support. The Zionist project is 90% dependent on constant material aid from Western powers to prop up its regime and would be forced to concede to the larger and more committed Palestian liberation movement without it. If they were to do anything active that was helpful, it would be to denuclearize Israel first.

Both of this things would require significant changes, though. Israel is propped up because it’s violence against its neighbors is useful for US domination of the region. But we can work for this in pieces by blocking arms exports, disrupting supply chains, and builsing leverage to demand that countries spend domestically instead of supporting genocide. Ironically in EU countries it is far-right electoral groups that have more steam for the latter due to the fact that liberals have made themselves the warmongers focused on increased militarization, but of course we cannot trust those right wingers to follow through.
