Compliant politicians don't necessarily have to get anything in return. Punishment and the threat of it can motivate behavior, just like positive reinforcement.

Anyway, I wouldn't personify these countries and assign them motivations. Geopolitics is complicated, and there are many people pulling strings across many nations, complete with complicated rivalries and partnerships. The support for a modern Israeli state in the first place started outside of what is now Israel. So, you can't assume pressure to support Israel all comes from Israel itself, purely in its self-interest.
