Chetniks to join Nedić's regime to launch attacks against Tito's Partisans. Mihailović saw as the main threat to Chetniks and, in his view, Serbs, as the Partisans who refused to back down fighting, which would almost certainly result in more German reprisal massacres of Serbs. With arms provided by the Germans, those Chetniks who joined Nedić's collaborationist armed forces, so they could pursue their civil war against the Partisans without fear of attack by the Germans, whom they intended to later turn against. This resulted in an increase of recruits to the regime's armed forces. 1942 In December 1941 and early January 1942 Chetnik leaders from Eastern Bosnia including Jezdimir Dangić in alliance with the government of Milan Nedić and the German military leadership in Belgrade negotiated about secession of 17 districts of eastern Bosnia and their annexation to Nedić's Serbia. During this negotiations was formed temporary Chetnik administration in eastern Bosnia with intention of establishing autonomy while the area does not united with Serbia. At that time it seems that the Chetnik movement had succeeded in creating initial basis for "Greater Serbia" but with diplomatic activity of the NDH authorities toward Berlin attempt to change state borders of the NDH were prevented. 1943 In January 1943, Nedić proposed a basic law for Serbia, in effect a constitution creating an authoritarian corporative state similar to that long advocated by Dimitrije Ljotić and his pre-war fascist Yugoslav National Movement. Bader asked the various agency heads for their views, and despite some specialists recommending its adoption, Meyszner strongly opposed it, seeing it as a threat to German interests. Passed to Löhr then to Hitler, a response was received in March. Hitler considered it "untimely". Nedić during negotiations with Hitler and Hermann Neubacher was arming and organising Bosnian Chetnik bands with attempt to expand his influence into East Bosnia. One of Mihailović's closest personal friends and collaborators, Pavle Đurišić, simultaneously held a command for Nedić, and in 1943 tried to exterminate the Muslims and pro-Partisans of the Sandžak region. The massacres he carried out were compared to the Croatian Ustashe and Muslim massacres of Serbs in the NDH in 1941. Nedić was received by Hitler and German foreign minister Joachim von Ribbentrop at Hitler's Wolf's Lair on 18 September 1943, where Nedić requested the annexation of East Bosnia, Montenegro, the Sanjak, Kosovo-Metohija and Srem but this was rejected.
