Ukraine & Russia were already using them. The issue is about the US opting to replenish Ukrainian stocks. I am very uneasy about it, removes much of the moral high ground. I would rather the US found the missles needed instead. But I understand why, as they aren't using them, the nations at war are; and the Ukrainians need to oust their enamy from dug in locations. Not an easy decision to make whatever was chosen. But overall I disapprove. We didn't sign up not to use them for no reason.
