If the United States loses the economic weapons of control, it is very much weakened.

The former colonies, in Latin America in particular, have a better chance than ever before to overcome centuries of subjugation, violence and foreign intervention, which they have so far survived as dependencies with islands of luxury in a sea of misery.

There are cases - for example, the American Revolution. George Washington's army lost just about every battle with the British, who had a much better army. The war was basically won by guerrilla forces that managed to undermine the British occupation.

Melting of the huge Antarctic glaciers, proceeding more rapidly than anticipated, threatens a rise in sea level that will drive tens of millions from the low-lying plains of Bangladesh alone, with disastrous consequences elsewhere.

I think a decent society should protect rights to private property within limits, but not concentrations of private power that infringe on the freedom and rights of others, including exploitation of labor, and that convert any democratic forms into what have been called sometimes "hierarchical democracies," like ours, in which some have vastly greater influence over public policy than others. Spelling all of this out is a complex matter that raises many issue and problems that are impossible to address here.

What's the purpose of NATO? Well actually we have an official answer. It isn't publicized much, but a couple of years ago, the secretary-general of NATO made a formal statement explaining the purpose of NATO in the post-Cold War world is to control global energy systems, pipelines, and sea lanes. That means it's a global system and of course he didn't say it, it's an intervention force under US command, as we've seen in case after case. So that's NATO.

That's unfortunately common - to blame immigrants, to blame the African-Americans who are being helped by federal programs, to blame anyone available, to direct attention away from the roots of the distress which you're suffering. This combines with xenophobia, white supremacy, racism, misogyny, and other quite unpleasant phenomena which are far from being eradicated. All of this makes for a pretty dangerous brew. But economic issues are right in the center of it. And you can see this in the fact that so many former Obama voters now voted for Trump, or just didn't bother voting.
