And if we were to capture 50 of his highest level supporters, this scenario would be repeated 50 times.
If we declare war, then these bastards get to be slammed into POW camps. Perhaps these could be conveniently located outside of Barrow, Alaska, for their convenience.
Once in the POW camps, these individuals would be entitled to three squares a day and periodic mail delivery. And, as prisoners of war, they would be incarcerated for the duration of the war.
And the war wouldn't be over until WE say it's over.
Might take years! Decades, even.
Since our enemies do not wear uniforms or anything else which identifies them as soldiers, they are not entitled even to treatment as prisoners of war. They are war criminals, and even those we capture alive can be tried in front of a military tribunal and, if convicted, executed.
I wish I thought we had the guts to do it.
A declaration of war allows us to do what MUST be done to eradicate them and their abetters.
