I hope the US has the good sense to abandon the ISS in 2024 as well.
It served its purpose as a useful tool both to explore human space flight and perform science, as well as a mechanism to encourage world peace among superpowers... but with Russia gone and China prohibited from participating, it cannot fulfill the latter mandate and it is antiquated and outdated in regards to the former.
Axiom, Blue Origin (snerk) and others are planning orbital installations of their own. Vacating ISS from orbit will drive more commerce to commercial installations that are newer, sleeker, and less maintenance intensive.
Also, no remaining international "partners" have human spaceflight capability. ESA is handicapped due to the Russia/Ukraine war and cannot acquire Soyuz/Vega hardware, and is caught flat-footed between their Ariane V and Ariane VI vehicles. JAXA was always a low priority program for Japan.
NASA currently spends about $3.1 billion a year on ISS. NASA currently spends about $6.8 billion a year on Artemis and wants to increase that to at least $7.5 billion or higher in the coming years. Leaving the ISS behind makes that quite easy, and allows for NASA to continue LEO operations as a customer of Axiom, Blue Origin (snerk) or some other LEO laboratory operator.
I also believe that bowing out of the ISS program would likely drive ESA to finally develop their own human spaceflight program. It's irked me for years that ESA lacked this capability. I suspect that India's ISRO will beat them to it.
Now is the time though, to support the direction LEO operations needs to go. ISS without Russia will be a financial anchor for the US to carry alone. It also was engineered from the get-go to have certain tasks performed by the Russian modules, and altering procedures such as orbital boosts will result in changes to center of gravity and thrust vectors to the station. It's too old and fatigued for that.
