(Hour 2.) A new age of terror begins in the aftermath of 9/11; fear becomes a weapon as America and its allies face a new brand of enemy in an unconventional conflict that demands an evolution of warfare as we know it. The American people adjust to a new normal of heightened security at home to prevent another attack. Abroad, the conflict that begins in Afghanistan spreads to Iraq and ultimately morphs into a global battle, as coalition efforts to eliminate the scourge of terror unintentionally give rise to ISIS. As the Islamic state becomes increasingly difficult to contain using traditional military tactics, its dark message spreads around the world through social media, gathering recruits and inspiring the first lone wolf terror attacks in Paris and Brussels.
