Hard to say what’s needed anymore. Obama signed on (illegally w/o Senate Approval) to the Paris Climate Accords, IIRC.
Regardless, I’d say the way to diminish NATO is to just not include any funding or operational orders supporting it. NATO has become a lumbering behemoth going far beyond its original charter. If Europe and some here in the US want NATO-like involvement in the mideast, then create a new treaty and get it passed through the Senate and stop piggy-backing off cold war NATO.

And because it did not constitute a treaty no president since is required by law to follow it.
Presidential agreements not signed as a treaty approved by the Senate have no force of law, to any administration that does not feel bound by it.
A treaty approved by the Senate is different, in law. It is pretty near to, but not as strongs as, a Constitutional amendment but considered part of “the Supreme law of the land”.
I think the “new” legilsation was not needed to keep the U.S. in NATO without the Congress agreeing to dissolve a U.S. treaty arrangement.
