After whats happened in Iraq, i doubt U.S. will be invading another muslim nation for at least another ten years. And why would U.S. invade Pakistan, there isnt a heap lot of oil and Pakistan is a nuclear power and the U.S. would expect at least 10,000 casualties invading Pakistan.
And the guy who wrote it is an idiot. The real threat to U.S. cosy monopoly of superpower status is China and the eventual conflict over Taiwan.
The U.S. has become so engrossed in bombing sandal wearing Muslims that it has forgotten that China is developing a major military power capable of challenging the U.S.
And the U.S. foreign policy will alienate it further from the Muslim world if it attacks pakistan which will be costly in its upcoming conflict with China.
