What that conveniently ignores is that "of territory that the terrorists view as their homeland or prize greatly" no longer means the country  the terrorist is actually from. It means any Muslim-majority country, i.e. it is based on religious grounds, not political ones. 

Someone officially American, or German, or Belgian, or French, or Tunisian, etc., actually identifies more with people of their religion in another part of the world, based solely on a common religion.

Imagine if Christians or Buddhists were to commit acts of terrorism in their own country or another in support of  other Buddhists or Christians in a totally different part of the world based solely on a shared religion....
