The war on terror enters a new phase as home-grown lone wolves begin to strike in the US. The American military apparatus struggles to contain a threat that has moved to a new battlefield: the internet, where ISIS and other terror groups enlist and inspire individuals to commit acts of terror anywhere they can, posting instructions and even hit lists. Tragedies in Boston, San Bernardino and Orlando are stark reminders that despite all the increases in security, the threat lingers. New and unexpected allies join the counter offensive, including hackers and US businesses. But a climate of fear gives rise to more hate, and a new wave of domestic terror emerges, led by white nationalists.
