MOSCOW, April 18. /TASS/. Russia will carry out a technical inspection of the International Space Station and will make a decision on withdrawing from the project since 2025, and will inform its foreign partners.According to Russian Deputy Prime Minister Yuri Borisov’s administration, the timeframe of the station’s operations has expired and its condition leaves much to be desired. "Lately, reports about technical malfunctions have been coming more often. In order to avoid any risks in case of accidents, it’s necessary to carry out a technical inspection of the station. After this, a decision should be made.""And they [partners] should be fairly notified about the withdrawal from the ISS since 2025," Borisov was quoted as saying in Moscow. Kremlin. Putin program on Rossiya-1 TV channel.
So assuming Russia goes ahead with the pullout, what should US do:1. Should US abandon ISS and bet everything on Axiom (or other commercial station provider)?2. If US wants to save ISS after Russian pullout, how to do it (2024 version)?
Russia to NASA: Send us money or else.

How is it done? What can be done aboutCould the Russian Segment be Separated from the International Space StatioReplacing Russian Functions at ISS But the situation on the ground also changed significantly, by 2024 US will certainly have 3 cargo ships, 2 crew ships, more advanced satellite servicing vehicles, maybe Dragon XL and Axiom core module, probably Starship too.So assuming Russia goes ahead with the pullout, what should US do:1.

UM has some lifespan shortening issues so they are dropping plans from undocking MLM-U and UM from SM. Besides successor ROSS is now to be built at 98° inclination at direction of the MoD involvement ROSCOSMOS oversees construction and operation, Glavkosmos handles all of commercial and domestic aspects and MoD in change of domestic military payloads and instruments.A paywalled write-up: http://russianspaceweb.com/protected/ros-um.html

If so what will they do with the existing modules? Deorbit them? Leave them on ISS (Sell them to NASA)? Would NASA be able to operate their modules?

Only Progress can reboost and refuel the ISS. When Progress ceases to be available, or looks like being unavailable soon, that's the end of the ISS - it will have to be deorbited.

Good luck on your collaboration with China. The post-ISS Russian plans - sketchy though they are - seem to revolve around a vehicle that is the same size and shape as the add-on lab modules for the Chinese space station. Have a look at RussianSpaceWeb.com. I could easily see Russia extending their previous collaboration with China and it offering both parties advantages.

NASA owns the FGB.
...And the Service Module (Zvezda) is where the presumed leak is located? So how many wires would need to be manually cut to jettison Zvezda and everything aft of there from the US segment?
The final inclination selected for CSS prevents Russian involvement without taking prohibitive mass penalties.
