The Department has noted with considerable apprehension increasing propaganda rumors and semi-official statements in favor of an autonomous Macedonia emanating from Bulgaria, but also from Yugoslav partisan and other sources with the implication that Greek territory would be included in the projected State. This Government considers talk of "Macedonian Nation", "Macedonian Fatherland", or "Macedonian National Consciousness" to be unjustified demagoguery representing no ethnic or political reality, and sees in its present revival a possible cloak for aggressive intentions against Greece.
