Obviously it is easier to destroy terrorists when they are on Pakistani territory permanently rather than just run into Iran then quickly run out again...
One side you say Pakistan cannot guard the border, then you tell us how easy it is to guard the border.
We understand Pakistan doesn't want to remove terrorists safe haven, you don't have to, just let us deal with it for you in a brotherly spirit.
We are already doing this, we shell the terrorists inside Pakistan regularly.
But we shouldn't have to do this, I would prefer brotherly and friendly relations with Pakistan where we work together to fix this problem on the Pakistani side.
Clearly you know nothing, it is almost impossible to stop 'hit and run' attacks like this, Israel suffered from it many times and that border is much much smaller than the Iran-Pak border.
