Mali has a significant mine that France essentially controls. In America, we have mines but import a lot too.

We actually currently buy about 25% of our uranium supply from Russia, though Congress just passed a ban that’ll go in effect in 90 days. It allows for waivers if there are supply issues, though, so it might end up being more than 90 days. (I have no idea how quickly a country can find a new uranium supplier but it sounds complicated.)
