I understand the sentiment. However nations are made up of people, the vast majority of whom have nothing to say about what their govenrments do. To even speak out against the government may cause severe repercussions in most nations in this world. These people for the most part are just plain everyday folks, trying to get along and raise thier faimilies.
A better idea is to go after the people responsible and those who aided the acts. Simply nuking a nation is an insane act since 99.999999% of the people have nothing to do with the act.
Tough $hit! Like the a$$hole Palis dancing in the streets in Lebanon and on the West Bank and Gaza, they support the terrorist war effort, in the most generous cases simply by being.
Kill them all ... nits make lice!
Ok let's assume you're right for the moment.
Let's give the population of the capitals of Afghanistan, Iran, Iraq, Syria, Lybia and Yemen 48 hours to evacuate and then destroy those cities.
THEN
Give the 99.999999% you mention 24 hours to turn over their know terrorists.
If there is no response, then, start reducing the population.
Speaking of insane, how do you characterize today's incidents?
And how can you deal with the violence of insanity with calm deliberation?
