You are more than entitled to your opinion, but your opinions have very little basis to them. You really seem to be on here to just take an opposite view with no real merit.
What specifically makes you think the USA would nuke some country or countries, given the current makeup of our government, in response to suffering a terrorist nuke attack?
Who would they nuke? There would be no consensus to nuke anybody based on the actions of a few terror cells who got their hands on a nuke.
Can you share with me specifics, of 'real merit?'
