I think that the main reason for the violence with Pakistan is not the partition of India and Pakistan in 1947, but this violence has increased because Pakistan is a Muslim state and India is a Hindu state. Especially since Modi's BGB Hindutva political party came to power, the anger of Indian Hindus against Muslims is increasing. In India, you will find a lot of evidence of atrocities on Muslims including the destruction of mosques. You will not even find any Muslim state that is a friend of India. Even the neighboring countries do not have good relations with them only because of their arrogance and religious differences. I see religious differences as the main reason for this conflict with Pakistan.
BJP came in power in 1976 with their roots are long with they killed Gandhi and also have many other things through RSS and then VHP, so I strongly believe they are still not accepting Pakistan as state this is main reason.
In last 50 years Indian all elections are having Pakistan factor due to BJP so its main reason behind this even they well aware they can't do anything but due to few big players they have done this and now having themselves in serious trouble because they were expecting good response from world, but just Israel is with them many others are criticizing this Pakistan can give them good response, and they surely will do in near future.

Attacking on these places clearly indicating what is mindset of these coward peoples and what they are thinking even their Foreign Minister frequently talking about democracy and human rights, but this attack is clearly giving impression about their policies.
