Other than a few money driven politicians, and those are not true patriotic Pakistanis, we don't really give a flying F about UN or you for that matter. RAW/CIA puppets TTP are being dealt with ruthelessly, and we don't even need 600k soldiers in those areas to do that.
Both sides support certain movements across the borders, so no one is a saint. To say one is more to blame than other would be plain foolish as ISI and RAW operate well across the borders and have been for decades. If we are supporting the Kashmiris, you are supporting TTP, BLA & MQM. You supported Tamil Tigers in Sri Lanka, and we supported Sri Lankan govt!
Next war between us will be the bloodiest, if it happens, and you and I will most likely not survive a nuclear war (conventional war is highly unlikely now). So let us both hope that it doesn't come down to that.
