It is not doomsayer crap it is reality, and also I dod not know japan upped titanium production, because for many years it was russia and africa being pretty much the only major suppliers, so much that the sr-71 relied on the soviet union for tianium, through a fake company to buy titanium from the soviets to ship to the united states.
United states being number 9 does not mean much, when the world is using aluminum more and more by the year, infact china has vastly increased production, being the largest seller, followed by india which barely beat russia then russia, the united states would have to more than triple aluminum production to match russia.
This also still leaves out the ones you avoid, fuel which the entirety of europe needs for it's economy to function, also russia is the largest exporter of wheat in the world. Russia is also one of the larger producers of copper, nickel, and platinum. Russia also holds around 6 times the amount of rare earth materials the united states does.
If you look at everything from high end chips to catalytic converters and high end weapons, things are moving more and more towards everything russia has, or china has, so from an economic standpoint sanctions are not going to do much to russia but rather hurt europe more than anything.
