Just for shits and giggles, Germany should invade Kaliningrad Oblast to help save the German-speaking population that was so ruthlessly cut off from Germany after the end of WWII. They could change the name back to Königsberg and then give it to Poland as a gift for that whole Lebensraum thing and you know the other stuff that my crazy racist neighbor Mike says is fake history.

Then Poland in a show of friendship and solidarity could gift it to Lithuania and they could go back to calling it Lithuania Minor. I think this is a solid plan that benefits the oppressed German speakers and re-unifies this long-lost region to its ancestral homelands. Also, throw something in there about stopping nazi governments and child trafficking just to be safe.
