A real nuclear warhead should be stored appropriately on a military base and not, I assume, wide out in the open in the middle of town. It doesn't look like any currently operational ICBM to me, either. Whether it's real or not, it shouldn't 'shake you'.
unless you do in fact live near a military base; in that case, you happen to be one of several dozen direct targets for a missile attack if a nuclear strike is ever launched against the U.S., so then I guess someone else's missiles are gonna blow up all those real missiles, and THEN you'll blow up
