I've only played two full games FTR - and my understanding is draws are fairly common. So if the the remaining countries ever recon it's stalemated, it's fine to agree a draw! Though obviously also fine to try your luck & hope you don't get fucked over and end up with nothing!
Also with remembering that if all folk press ready it progresses quicker, which can be a good idea when there are fewer folk left / you just want to blast through sine turns. But all up to whoever's left really!
