So you want to defeat “radical terrorism”? Are you OK with leaving the regular kind alone?
And why “terrorism”? Did FDR declare war on “torpedo planes”, or on those who sent them?
I understand the question but I do not see your point. Are you ill?
As far as I know torpedo aircraft were not designated as "terrorism" at the time. They were weapons in a declared war; one government against another with uniformed pilots, sailors, and soldiers.
So what is your point if you have one?
