When neighbors are rogue, your intervention become more necessary because any rogue country like china may bribe their politician and get a foothold in that country and threaten our national security. We have to be vigil all the time. these shitty nations can cause damage to our national security. It is very much necessary to have a friendly government in Srilanka, BD, Maldive, Nepal and Bhutan and Pakistan. It can not happen in pakistan but , we must be very vigilant to have friendly government in other places. Modi has established a friendly government in Srilanka but some times Nepal and Maldive becomes very important and chinese activities have increased a lot in these nations.
Alliances and Friends made on brides don't last long. Look at what happened between USA and Pakistan. Pakistan got thousands of its people killed.

Just keep watching this space the people they got bride to train as Mujahidin that is Pashtuns are going to put their foot behind Panjabi Paki ass.

The best method of learning is self learning.
