Do we even have a great need for Greater Khem coaling stations with the Khemetri taking that place? I assume it wouldn't be much of an issue that we have a treaty that we get to use each others coaling stations.
So while everyone goes crazy over Greater Khem, we go into SEA and start selling guns, industrial gear and advisors as we have been doing already and generally try to do a hands off approach. (Maharatha may come under the train but a lot of others won't!)
Also, that's area we can actually somewhat project power into, unlike Greater Khem.
As for releasing nations after they want us gone, given the likely expenses our politicians will look for excuses to get rid of them while keeping trade deals. Like making our own Commonwealth. Or UdSSR.
