The CIA programs spanned some four decades. Starting as a paramilitary operation that provided funding and equipment for such anti-Soviet Ukrainian resistance groups as the Ukrainian Supreme Liberation Council (UHVR); its affiliates, the Organization of Ukrainian Nationalists (OUN) and Ukrainian Insurgent Army (UPA), all Nazi Banderists. The CIA also provided support to a relatively anti-Bandera faction of the UHVR, the ZP-UHVR, a foreign-based virtual branch of the CIA and British MI-6 intelligence services. The early CIA operation to destabilize Ukraine, using exile Ukrainian agents in the West who were infiltrated into Soviet Ukraine, was codenamed Project AERODYNAMIC.
