I believe Italy has nukes as a NATO participant in nuclear weapons ‘sharing’ with the US. If so, the equation looks a bit different. The fact that we are addressing this at all is disturbing, and tells us how far in the wrong direction the world has moved. It’s way past time to fix this mess.
Yes, Italy hosts an estimated 60 - 70 US tactical nuclear weapons (as of 2011).
Kinda hard to nuke an enemy that’s mixed in with your population.
