True, but it required congressional approval to change the name then, and it would now as well.
This congress is not likely to approve it. And the next congress, even less so.
That said, "ever" is probably too strong. There's a window wherein the chaos which is currently being actively created by the US will develop to an extent that compels the US (or is sold to US voters as a necessary step) to adopt a foreign policy where it would be the more appropriate title. And if the adults can't manage that with charismatic leadership in the next election cycle or two, we could be right back here again, with quasi-legitimate geopolitical justification for the sort of big-stick wagging we see today.
I honestly think this is the goal, and I'm not sure the American people are up to the challenge of preventing it.
