Note that Germany have basically the same anthem since 1922, but each time their system change, they change which stanza goes first. Now only the third is considered anthem, first being too fashy and second too silly.

Poland fact: Polish anthem is also very revanchist but nobody give a fuck to change the text, there's even very high praise for Napoleon Bonaparte left in second stanza (and very ironic one that Bonaparte shown us how to win)

Poland fact 2: contrary to what anyone could think, there is not a single mention of God, Mary or anything religious in the Polish anthem.
