Re: Polish contributions
It seems odd how so much relatively recent history, is still being discovered.
Not really. Wartime secrecy and deception morphed straight into both cold-war intrigue and the politics of zionism and modern Israel. Lots of powerful players with enmities, suspicions, and propaganda Agendas that have changed over the years but are still with us. A historian is faced with obstacles ranging from state-enforced secrecy to weaponised taboos.
