"Three or four tactical nukes set off one day (one week, etc)at a time would effectively end the US as we know it.
Never underestimate the enemy."
And ten in the ten industrial cities would cause world chaos. The US would be forced to nuke every islam country to green glass.
We would not do it. The liberals and panzies would be screaming that we would only be killing innocents and that nothing would be gained, count on it.
