You can make all uber-weapons vanish.

With a thought, you can make all weapons of mass-destruction disappear along with the ability to make more. No more nukes, atomic bombs, ICBMs, things that can make cities and villages go away in an instant. All people are aware that these two things, the weapons and ability to make more, are gone. They do not know you are the cause.

Would you take/not take nukes off the board if you could and why?
