>>510548364 (OP)America + its vassals will be enough for Israel to get full-spectrum dominance. Most of the top 20 biggest economies are US vassals, or at least influenced by the US.
So Israel will just keep pushing harder to delete the remaining noncompliant regimes. (like Assad, Gaddafi, and now Iran.)
Then it won't matter if the US falls, the world is already theirs.
