So I talked to a PhD who's work covered civil wars across the world, and asked about this. Turns out there are several signs you need to see which makes a civil war more likely. Most of which we haven't even gotten close to, because many of them are economic related and right now the US is still the single largest economy in the world where peoples standard of living is still very comfortable.

I asked ChatGPT to describe this and these are the highlights, in order of historical priority?

• Political instability and weak governance are present.
• There are deep ethnic, religious, or sectarian tensions.
• The economy is declining with high inequality.
• Persistent social unrest and widespread protests occur.
• External powers are interfering or supporting different factions.
• There is significant resource scarcity and competition.
• Militarization and proliferation of arms increase.
• Systematic human rights violations and repression take place.
• Society experiences strong ideological polarization.
• Demographic pressures such as rapid population growth or urbanization exist.
• The rule of law and justice systems are breaking down.
• Historical grievances and unresolved conflicts resurface.

Note that the US does have some of these, but not to the evident level that you saw in Rwanda, Sudan, Yugoslavia, Syria, Burundi, Eritrea, Somalia, Libya, Myanmar, Haiti, and others. In short, if you look at the indicators, although the US is indeed troubled, it's not troubled enough for people to hot the streets with more than riotous intent.
