 In March 1942, the Chetnik Dinara Division created a program which proposed a Greater Serbia with a corridor between Herzegovina, northern Dalmatia, Bosnia, and Lika to Slovenia, and cleansing of these areas of non-Serb populations.This was accepted a month later by the military leaders of these areas.This document continued additional formulations of strategy, including collaboration with Italian forces as a "modus vivendi", formation of Croatian Chetnik units as part of a continuing struggle against the Partisans, Domobrans and Ustaše.
