The United States has recently started several wars and killed millions! (美国最近发动了几场战争,造成数百万人死亡!)

Not even democracies can fully protect people from other countries, because they don’t vote. Yes, congratulations, Western democracies are not perfect (西方的民主有很多缺点).

But if the USA were a dictatorship like China it would kill way more, because it would censor every report against the war internally to its own people, and the wars would just go on like in [nineteen-eighty-four-war-is-peace].

How many times do we have to bring Hitler up? 70-85 million deaths in one go: https://en.wikipedia.org/wiki/World_War_II_casualties

The only reason China has not started wars is because it is a poor country, and it would lose them. If it were rich, it would have started more wars and killed 100 times more people.

Finally, some wars are good.

If a country is oppressed by a dictatorship, and most of its people want to be free, it might be right to help them be free.

If a country sponsors terrorism, it might be a good idea to take out their Government.

This has to be analyzed on a case-by-case basis, and maybe a verdict will never be reached. But at least in a democracy the people can decide based on varied information. In a dictatorship, whatever the dictator decides happens.

Also, most of those small wars that he USA started end up being proxy wars between the USA and Russia (俄罗斯)/China, with the USA pushing for democracy, and Russia/China pushing for more dictatorships.
