Ex-CIA insider: Paris attacks reveal "whole new world" of terror

The Paris attacks are the third major operation claimed by ISIS in just over two weeks.

Morell: Paris attacks were manifestation of ISIS' year-long effort

A Russian jetliner blew up over Egypt, killing all 224 on board. U.S. officials say a bomb was the likely cause. And last Thursday, twin suicide blasts in Beirut killed 43.

But after Paris, "we're in a whole new world," according to Michael Morell, a former number-two at the CIA and now CBS News senior security contributor.

In the video above, he explains why the Paris attacks change everything -- from the capabilities of ISIS to what is now considered a target.
