Had to write for a discussion in history guys, im scared to submit though, so how does it sound?

The question: What are the dangers of dictatorships?
Compare and contrast dictatorships during World War II and the twenty-first century.

"Dictatorships are dangerous because they take away freedoms, violate human rights, and concentrate power in the hands of a few. During World War II, dictators like Hitler, Mussolini, and Stalin were all about extreme nationalism and used propaganda and violence to control people.
Today, countries like North Korea and Venezuela still silence opposition, but they face more global scrutiny. They might use technology to monitor people, but that same tech can sometimes help people speak out against them.

Despite the changes over time, both WWII and modern dictatorships can lead to social unrest, economic problems, and serious humanitarian issues, all of which threaten individual freedoms and justice."
