 Sabrina Ramet, a political scientist, has observed, "Both the Chetniks' political program and the extent of their collaboration have been amply, even voluminously, documented; it is more than a bit disappointing, thus, that people can still be found who believe that the Chetniks were doing anything besides attempting to realize a vision of an ethnically homogeneous Greater Serbian state, which they intended to advance, in the short run, by a policy of collaboration with the Axis forces".A different view is advanced by the political scientist David Bruce MacDonald, who accepts that the Chetniks collaborated with the Axis forces to strengthen their hand against the Partisans, but claims that it would be highly misleading to suggest that the Chetniks collaborated in order to carry out the genocide of Croats and Muslims.The Chetniks were partners in the pattern of terrorism and counter-terror that developed in Yugoslavia during World War II.
