As other have pointed out - what commitment?
the Budapest Accession to the UN Nuclear Nonproliferation treaty that we signed, Russia signed, Ukraine signed. The Ukes honored it, Russia violated it by invading twice as soon as they found out there was oil & gas reserves there, and the USA is listening to pantywaist appeasers who are looking to abrogate our responsibility towards Uke sovereignty & borders, betraying them.
If we don’t get nuclear nonproliferation right, all those other countries are gonna try to develop nukes, because they cannot trust us nor the Russians nor the UN.
