[X] We insist on Lithuania.
We organized partisans in East Galicia on the premise that we'd be liberating them. The Polish people who rose up in resistance to help us are going to be treated like shit by the Tsarists. Leaving them behind after they've been shooting Russian officers for us is unconscionable.
Edit: Also, if we don't get East Galicia, then we have minimal access to oil in the next war. Given that it'll likely be in the '20s, with the plane and the tank being key to breaking extensive Entente fortifications, do we really want to do that?
Edit 2: Guess I'm changing it for the new voting options. What the hell, let's go.
