It's the pinnacle of undemocracy to impose democracy on an undemocratic nation.
It's no different from the way the former USSR used force to force communism on it's neighbours.
It's no different.
That notion about "...I know this is gonna hurt,but it's good for you,I'm doing it for your own benefit..." only works with your parents telling you what to do and not what to do,irrespective of how you feel about it.
It doesn't work in international situations.
