Intermarium
Intermarium (literally "between the seas") refers to the geographic territory between the Baltic Sea and the Black Sea. It covers much of the territory known as the Pale of Settlement and what Adolf Hitler targeted for "Lebensraum."
Prometheism or Prometheanism was a political project initiated by Józef Piłsudski, a principal statesman of the Second Polish Republic from 1918 to 1935. Its aim was to weaken the Russian Empire and its successor states, including the Soviet Union, by supporting nationalist independence movements among the major non-Russian peoples that lived within the borders of Russia and the Soviet Union.
Prometheism neatly overlaps with the CIA's Operation Belladona, Operation Aerodynamic, etc., which sought to work with nationalist groups like Organization of Ukrainian Nationalists (OUN) to counter Soviet influence and, essentially, create a breakaway state.
Piłsudski believed that "[w]ithout an independent Ukraine, there cannot be an independent Poland." And the exploitation of nationalism in the Ukrainian Soviet Socialist Republic became a key pivot in the Promethean grand strategy.
Adolf Hitler saw the region as a key to the eastward expansion of German lebensraum — or "living space". During the World War II, parts of the Promethean League became willing collaborators of the Nazi war machine, feeding it intelligence from what Germany deemed its "Wild East".
The project continued after WWII, with the US Central Intelligence Agency taking the place of the German Abwehr (military intelligence). The CIA actively recruited fascist collaborators from Belarus, Estonia, Latvia, Lithuania, Poland, Ukraine, and beyond — absorbing them into security agencies and establishing intellectual centers in exile that aimed at powering reaction back home. Declassified CIA documents reveal the intention to "exploit nationalist cultural and other dissident tendencies in Ukraine" and "exploit the minority nationality question in the Soviet Union".
