I do too.
The point here, is it is their nation, their laws, and their sovereignty. Using as an excuse that we don't like how they run their nation as an excuse for war is just as much bullshit.
Far more innocents would die in a war than we believe are being unjustly put to death. Governments, no matter where, don't really care about people, they just use them as an excuse to act more authoritarian.
If folks take this to its logical conclusion, then the entire planet could declare war on America for our allowing citizens to be armed.
Only a handful of other nations allow their citizens to own guns, and the hurdle for them to be armed is much higher than it is here.
I'm willing to bet far more people die of gun violence than Iran has killed by being oppressive, I have no doubt. But our nation has made the decision that an armed population is the only security of liberty. Their nation has decided that an oppressive theocracy is the only guarantee of public morality.
