Who's A Loser In A Proxy War?

Obviously, the one which is an elected government, one who is signatory to a whole lot of treaties, one who is accountable to world bodies like the U.N. and is usually the one who is reined in through any resolution, one who has a possiblity of embargo against it, one who has a lot at stake if it doesn't pay heed to the call of other nations.

Isn't an outfit which is not accountable to the international community, or to any world body or to any state, always the winner; especially when it demands an ethical, moral and (paradoxically) a diplomatically lawful treatment that the nations in the world usually offer to a legitimate state? There's nothing official in it that can be reined in. Win-Win. Eat your cake, and keep it too.
