I think it's kind of ASB to have them stay at those borders and never seek to expand further and have the allies accept this. But if that's the case, they're still pretty strong. It's basically modern Germany, Austria, Poland, the Czech Republic, and most of Slovakia. The GDP alone would be enough to make them a European juggernaut over the next decades. Pair that with the fact there'd be friendly governments in Hungary, probably Romania, and maybe Italy depending how things shake out, and there's firm groundwork for a central European bloc to oppose Soviet expansion. But as I said, this borders happening without war or an appetite for MORE territory is basically ASB.
