Putin has used energy as a weapon and taught the Europeans how stupid they were, especially the Germans to be dependent on Russian natural gas. So many bombs and shells have gone off in Ukraine right now that there's almost no base metal left in inventory. Every time a shell goes boom, you need copper and antimony and other metals that are not recycled. And so we are living in a much more dangerous period than we were a year or two ago. We're already in an energy crisis. It could be much, much worse. Hopefully it won't happen, but we see huge increases in the price of food globally that will hurt marginal societies like Egypt, Nigeria, Pakistan.
