I agree that this is a great Nuking opportunity but with all due respect what happens next? You will have not just a country but an entire region effected by this. There will be no opportunity for a government to be erected in its place and the reason most countries fall in to ruin is because leadership is abolished and given up for grabs for the people to fight over who would run the country better. It would cause too much chaos in the long run and another militant group would eventually take its place in a radioactive land up for grabs.
Agreed . It's unlikely the nuking of Isis is going to change much other than there will be a lot less of them . All we can do is to try and contain them . By removing as many of them as possible through one nuclear strike will in some way do that for a while.
