I don't think there would move into a war following the breakout of the coronavirus.
But rather, people might focus a bit more on essential services for the time being. I wish there would be fewer bailouts for non-sustainable businesses to be honest. I'd rather see more free market movement other than more reliance on government.

If any conflicts is to arise, I doubt it would be in the form of war, especially not internationally. Riots are not related to international conflict, and don't have much to do with corona-virus. Maybe income inequality. More about internal conflicts.
