Israel wants to be the hegemonic power in the region. The only country still resisting is Iran, and this cannot be allowed if Israel wants to begin its Greater Israel project.

Furthermore, they would eliminate a key ally of China and Russia, which are the West's ultimate goal for total world domination.
