Ukraine seems to be what happens when a country willingly gave up their nukes (with US encouragement).

I have no problem if the US navy wants to tool around shipping lanes for the good of global trade. I take issue with everything else.

In the past couple of years, the US has implicitly used the strength of its military to threaten the sovereignty of Greenland, Panama, Canada, Mexico, and Cuba. Abducted a foreign head of state. Started a war. Bombed drug runners and fishermen.

The death toll for the Iraq war is heavily contested, but the numbers are somewhere in the region of 200k to one million dead. All under the guise of WMDs.

Like any large organization, there is a mixture of good and bad outcomes.
