Is the counterfactual definiteness possible at the level of countries?

I suppose, people here have heard about the Elitzur–Vaidman bomb tester and the counterfactual definiteness:

I have a question: can this experiment be performed at the level of countries for avoiding a nuclear war?

Let’s consider, that in 2300 A.D. there is a country with a dictator Kim 8, who oppresses the people, exports some resources and controls the overbomb which can totally destroy the planet. He is loosing power because of the sanctions, and decides to use a weird strategy – threatens that he will annihilate Earth if the sanctions will not be lifted. He does not want such a scenario, but he has a chance to win if the states will fulfill his demands because of fear.

What can the humanity do in this situation? They can annihilate the country of Kim firstly, but this is the violation of all international laws (the nuclear bombs can me used only in response). However, I think that theoretically, one more scenario is possible: the states can create a superposition of two Earths (two universes), in the first the apocalypses does not occur, and in the second Kim pushes the button. Like in the Elitzur–Vaidman bomb experiment, the information that Kim had done this in the second universe, will be accessible in the first universe, and this will give the states the right to annihilate the country of Kim.

What do you think?
