General Grievous is more like one of those pre-1948 Zionist terrorist leaders fighting the U.S.

On the outside it looks like he's overthrowing the corrupt institution, but really he's working for its secret government so that he can contribute to its total compromise and make it even more corrupt

If Grievous really functioned as a meaningful freedom fighter who sought to dismantle the oppression of governments, then he'd never target the vulnerable at the advantage of the Sith
