ISIS on a 'Different Level' Than al Qaeda, Says Retired General John Allen

ISIS is "better organized [than al Qaeda]. It’s command and control is better.”

ISIS is "better organized [than al Qaeda]. It’s command and control is better,” John Allen, the Special Presidential Envoy for the Global Coalition to Counter ISIS, told ABC News.

When asked whether ISIS is a threat to the home front, Allen said “we should take it very seriously."

After ISIS appeared to burn Jordanian pilot Lt. Muath al-Kasasbeh alive in a new video, Allen said the country was helping the U.S. against ISIS more than ever.
