Pakistan does play that game...
Does it threaten it’s neighbor nations other than India?
I think we could take India to task on that issue as well, but I believe India has to bluster to a certain extent just to remind Pakistan that it will pay a terrible toll if it uses it’s nukes.
It is interesting that the skirmishes between Pakistan and India subsided once the U. S. got involved with Pakistan during the wars subsequent to 09/11/2001.
