Unless Iran has received help from Russia?China? and they’re planning an invasion of the US after we’re in a weakened state.
If we were hit by an EMP attack, the last thing anyone would do is invade us, at least for a year, to give the food riots a chance to dampen out, and to take advantage of the millions of deaths such an attack would cause.
No need to invade. Iran doesn’t want our country, they want it destroyed.
