The US is complex antihero type.

While it definitely attacks threats and has perpetrated plenty of unjust deeds, it also is responsible for the food security of much of the world. It has lifted more people out of poverty than any other party. It has brought poor nations to the point of industrialization.

The US has been a far greater force for good in the world than evil.

The leadership changes frequently, so it's hard to point to any single responsible party. It's democratic, so its institutions are subject to scrutiny. The free press sheds light on corruption and rule breaking.

Despite changing immigration narratives, the US has been an early and strong proponent of multiculturalism and welcoming people.

With declining US hegemony, the world is likely to become a much more dangerous place. We'll see more economic strife, more war, higher costs, greater tensions.
