"researchers in Poland are working on the same problem."

It's amusing that Americans need a written document to believe in something that they can learn by themselves if they dare to go around the world just asking!

Go to Chile and ask who (and how) helped Pinochet's coup d'etate? and what about Argentina's militar Junta in '76? San Salvador, Nicaragua, Panama, etc., etc. And that is only in Latin America.
