Fareed Zakaria: The Goal Of ISIS Terrorism Is A World Divided (video)

'At home it will mean more domestic laws and tougher police efforts to monitor and arrest people. Given the news about terrorists posing as refugees, it could mean that borders will be closed. The government will spy on communications more intrusively. It will fuel the rise of nationalist politicians everywhere. And the mistrust between the Muslim and non-Muslim communities will grow.
It's worth asking, what does ISIS want? By most accounts, it wants all of this, a world divided between Muslims and non-Muslims. Its propaganda stresses that the West is intractably anti-Muslim. It has always openly tried to draw Western forces into Iraq and Syria hoping to make itself the great army of believers fighting the crusaders.

Imagine if the West could respond to these terror attacks with increased and more effective efforts both at home and abroad, but also with the determination to demonstrate that it would act, but not overreact. That it would reaffirm its basic values and it would strive to restore normalcy in the face of brutality.
