If everyone hates it, you only need to fight it if has external support. A regime needs considerable active support and even wider at least tacit support to operate; if everyone locally hates it, it cannot function as a regime (but, if it has sufficient external support, can perhaps function as an occupation, that you do have to fight.)
> I have no idea how you go about fighting one that half the country supports.
