Sense Sonnet - Chiller

Is...ic

The term, Islamic extremist
Is the focus of deep debate.
No doubt the problem does exist.
The I.S. means Islamic State,
Followed by I.S. or I.L.
I. for Iraq, L. for Levant,
Or S. for Syria, do tell.
One would think that termers would want
To briefly term the enemy,
Deserving of destruction worth,
And quickly make that a fact be,
Before the "blank" blankets the Earth.

Alphabetic enemy - yes!
Works, describing the I.R.S.!
