More than 200 Canadian Muslims traveled to Syria to join ISIS in full knowledge of ISIS's fascist Islamist ideology and of the multiple atrocities committed by ISIS.

Then I hear people saying we should let these people return to Canada for rehabilitation.

No, they should be jailed for a long time (if not already killed on the battlefield).

More than 70 years after the end of WW2 we are still hunting and jailing Nazis. The same determination must be shown in tracking down and jailing any Canadian who went to Syria or Iraq to join ISIS.
