USA spending trillions of USAian dollars and debt to fight an enemy its highest military people cannot even name. Or the name changes from week to month. ISIS, ISIL... The name of the enemy is known by real USAians. It looks a look like the Nazis buy pretends to be a _pieceful_religion_
One can only conclude that ISIS is not a real enemy, but a group of paid Gulf Arab operatives that we are permitted to publicly complain about but not to forcibly evict, lest much under-the-table Deep State funding be jeopardized.
