Homeland Secure?

One of the most pressing questions that America faces as a nation is why Al Qaeda has not launched another attack within the United States since 9/11.

Is it because America has created a successful system to defend its ports and borders? Is it because efforts overseas have Al Qaeda on the run or focusing elsewhere? Or is it simply that Al Qaeda moves on a longer time scale?

Tune in to hear possible explanations as to why the United States' territory has, so far, been spared another attack.
