If they are going to do such a thing, they had better not play around about it. If I had to do this, my approach would be a total destruction of ALL military targets, not just the nuclear and all factories that produce anything related to the military.
It would have to be done so that they would have NOTHING to retaliate with. Civilians must not be targeted at all. They will be the ones who will depose the leadership, once the military had been destroyed. The leaders of this nation have NO friends at all anywhere.
