Pakistan and India don’t like each other at all. With good reason. Pakistan’s intelligence agency has given support to Pakistani terrorists in India, who have killed hundreds over the past decade.

They have fought four wars in living memory. The relationship between India and Pakistan is one of the most hostile in the world today. Why?
