Is this program threatened by evolving geopolitics as well?
no, it would be another case where Russian would be doing more damage to itself
I think Russia would keep this program going, perhaps even increasing it. With the new Chinese-Russian space agreement, it seems to me to make more sense for Russia to try to increase cooperation with ESA. Pulling ESA towards the East would strengthen their new international bloc and weaken US influence.
So far ESA is keeping politics out of space cooperation, and if it stays that way nothing would change.
