I'm glad Jihadi John is dead but why is our warfare so personalized?

US forces have carried out a drone strike in Syria against the Islamic State group militant "Jihadi John".
A US military source said there was a "high degree of certainty" he had been killed in Thursday's attack near Raqqa.
PM David Cameron said although it was not yet certain whether the strike had been successful, targeting Mohammed Emwazi was "the right thing to do".
The Kuwaiti-born British militant appeared in videos of the beheadings of Western hostages.
It is believed there was one other person in the vehicle targeted in the strike.

Here.

I'm glad this bastard is dead.  Don't get me wrong.  He was pure evil and seemed to revel in his acts of barbarity.

But when did and why is our nation state warfare so personalized?

Think about it.  We sent a drone on a mission to kill one man!  I'm of the belief that the people that are operationally important are never seen on camera.  The people that make ISIS "win" on the battlefield aren't the guys making YouTube videos.

I might be way off base here but the battlefield is where it gets "personal", airstrikes should be looking to cause certain effects.  That one drone flight could easily have been used to destroy ISIS infrastructure, armored vehicles and training camps.  Instead it was used to hunt down one guy....a useful idiot that had blood lust.

Yeah.  The world is a better place with him dead....but is our war against ISIS served by using so many resources to whack him?
