As a Polish person who had Russian and German (English also :)) in school, so I can read those documents, I would say you Brits should get interested about it

As a Polish person who had Russian and German (English also :)) in school, so I can read those documents, I would say you Brits should get interested about it in 1939 not now. Those French guys also should chip in earlier. Don't take it personally it is a just historical joke!
