The only way we will ever remove nuclear weapons will be when we remove the threat from invasive and terrorist actions of other countries. We need an international force that is set up just to protect the status quo of borders around the world. With that we also need an answer to terrorism from foreign states. As soon as you make it impossible for an invasion to take place then you can guarantee that some states will head straight to terrorist acts for intimidation. Until all countries sign up to this, we must keep the deterrent.

Imagine how could be saved if we removed the need to spend on defence. Currently we spend $2.2t across the world on killing each other. It is a shocking waste.
