To be honest, the best targets (from Irans point of view) are NOT states that are heavily in support of Trump.
If your goal is to cause resistance and unrest in the population it is best to target the material conditions of the regions with high density populations. This is going to be "blue" no matter what state is targeted.
But, of course this is not reasonable in reality either. The targets are going to be those of opportunity. ANY security that can be exploited.
Iran is having bridges and civilian infrastructure destroyed by a country that attacked them in aggression. OUR country did that (if you're American). You're not out in the street everyday demanding it stop. You didn't stop paying rent demanding it stop. You didn't go on strike demanding it stop.
So, until Americans actually feel some consequences for their inaction, you're not special because you didn't vote for Trump. You're just as inactive against this war as a Trump voter that heard him say "no new wars" and nothing else. He's president. Pointing to the past saying you didn't want it does nothing. WHAT DO YOU DO NOW? Because if it was your schools and bridges I hope you wouldn't just stop at blaming Trump supporters.
We'd all be protesting, striking, and refusing to pay rent if we had our schools getting bombed because of our government. But we don't when the victims aren't Americans. We pretend we're not responsible and keep enjoying our comfortable lives while saying "I didn't vote for this" as a reason to remain inactive.
