I am not proposing to wipe out the Afghan People. I think a nice parting shot to serve to them a reminder nice to attack our country again or that we will deal with them harshly.
The idea is not to kill Afghanis. Most are probably very peace loving people if we met then at the grocery store or as neighbors.
The Nuke or something to that effect is a staunch warning to never launch terrorist attacks on us again.
Our inept war planning and strategy has made the Talibsn very powerful and I fear what they have planned once they take over. They believe in full scale retaliation.
