Supporting tyrants against their people on some feeble 18th century concept of 'sovereignty' is why we have the crisis of the last decade in the first place. Freedom for everyone or screw it all.
Out of curiosity, what is the “crisis of the last decade?” Honest question here, I’m personally not aware of any “crisis” that hasn’t been ongoing for several decades before the 2010s.
Wait, you actually want “America world police”? And who decides what is or is not democratic? In your world, what would you do against Saudi Arabia (I assume you’d see them as not democratic and thus not a real country)?
"Non democratic countries are not real countries." Lemme up the ante. Countries without free medicine and guaranteed basic income are not real countries". Someone need to come and teach them a nice lesson. "Screwing" will help as well.
