dude Pakistan is at war and you call it violence, you are a spin master again you say Pakistan sent in armed forces, dude at the time of Partition Pakistan had no Army, India got all Armed forces and equipment.that was suppose to be shared with Pakistan as were the other things like treasuries, factories, planes etc,etc.so you argument is strange and a spin.
According to the rule of partition the will of people was to be the main point of partition and by this Kashmirs were to come to Pakistan, when Nehru saw it he sent armies to not only Kashmir, Hyderabad, junagarh and other places. took all those areas by force.
