Why having common enemies help make new friends !

Larry Pressler, a long time advocate of India's interest is urging US to do cold-war reality check:

Freeing ourselves from our profitless Pakistan policy would allow us to look clearly at the biggest problem in the region: China. We should tell Beijing that we will help India match China's arms buildup and that we will work toward a modified free-trade agreement with India to help it offset China's state-dominated trade practices

This arms buildup talk scares me.
