Every year or two China bans exports of rare-earths to the US.

I don’t think anything China did made the Trump regime “feel the pain”. Lots of things Trump did made that, but China just doesn’t have that power over the US.

Well, compared to what the other side is doing, “nothing” is a lot more productive.

But he did do the normal “China is currently mad with the US” stuff, like banning the export of rare-earths.
