I am sorry, but where does Pakistan come into the scene in any of the above mentioned conflicts, apart from Afghanistan? The last time I heard Pakistan wanted to mediate talks between Iran and Saudi Arabia, but was booted out by both the parties.
I don't remember when was the last time Pakistan came in between Indo-China talks.
Similarly how is Pakistan affected with Russian, US/Turkey relations?
The only time Pakistan is mentioned in any world forum or summit, is when the issue of terrorism comes up. That's the only relevance Pakistan has in today's world.
