Yes..US very much supports terrorism so long as the terrorism is not against US. Without terrorism, how will all the arms dealers in US make money ? Without terrorism, how will US get rid of all its old stock. ?
US knows very much that Pakistan is a terrorist country, but so long as US is not hurt, it will turn a blind eye. Also, the only country to lose out due to Pak terrorism is Pak itself. Because the muslims in Pak are just being converted to terrorists, and then sent to India to get shot. Whereas Indians are getting educated, get jobs, run companies (many indians are CEO's of fortune-500 companies), etc. Pakistan and its muslims are just going straight to their graveyard only.
Only when the common muslim has brains enough to understand this, will he start shunning the terrorism path that the stupid Pak govt makes them take up.
