Certainly most of the people in Iran are similar to most of the people around the world. In kindness, compassion, in just trying to get their daily job done and enjoy time with friends and family. If only it was easy to distinguish between the good, the bad, the indifferent. Probably a lot of sanctions don't hinder the most threatening of Iran's activities, while impacting the population. But it does have an effect (not always the ones intended, perhaps).
If the government in power over you is in conflict with others, and/or in conflict with it's own people, it's going to impact you. If you want your life to be better, look for ways to improve your government. True for the USA and everyone else. Another lesson that the USA has been illustrating repeatedly recently is that it's probably better for a nations citizens to reform their government themselves, instead of a foreign power. Until that happens, yes their lives are not going to be as free as they'd like. It's hard and there is a cost to be paid for those freedoms. Many of us are fortunate in that those before us did the hard work and we get to enjoy the benefits. Good luck to the author of the blog, hopefully they can find good solutions.
