Just wait till the end of 2014
Where they were before USA came? Fighting India, or their own people?
Anyway, send your worst. All the Lashkars, Mujahideens, Talibs and other primitive lunatics will be sent to the same unmarked graves that their predecessors went to. India will not tolerate their nonsense, because they won't find sympathizers in India, like they do in Pakistan (you, for example).
The Pakistani army itself, with all its tanks and artillery and air support and tanks cannot challenge India’s might. Your bearded gunmen cannot do much either. I know it hurts to hear this, but it is true. Just because they have a beard and a Kalashnikov and a medieval ideology, does not mean that they can do jack against a stable, pluralistic nation like India with a professional military and police.
Even your Pakistani army cannot dream to take anything from India, so your bearded lunatics won't dream to dream. "Let America leave, then we will declare victory and conquer India" might be the latest motivational pamphlets the talibs distribute, while hiding in their caves until America leaves. Such threats may scare a rabbit. Courtesy- Janon!
