> The US is controlled by its greatest ally

I understand what you're trying to say, but this is fundamentally backwards. The US makes a conscious decision out of supposed self-interest to align itself with a state despite its history of instigating and spreading conflicts. It is not "controlled" by anyone. Saying so would imply that the US is somehow less responsible for continuing to support the state, and that the state somehow has ultimate control over US policy, neither of which are true.
