Tucović, who was drafted into the Serbian Army prior to the Balkan Wars, explained the crimes against Muslims as a part of the eliminationist projects of the Balkan states:
“These atrocities were neither initiated by individuals nor were due to personal distress, but were a constitutive part of the ‘national’ programs of the Balkan states. The Serbian Army was exterminating Albanians in Old Serbia (Kosovo) and Albania, the Bulgarian Army — the Turks in Thrace, and the Greek Army — the Turks and the Albanians in Devol — all in the criminal belief that they were attaining a ‘national’ aim — that by removing these innocent people off the face of the Earth [sa lica zemlje] they were removing an enemy with whom they would otherwise have to deal in the future.“

“There was a clear logic in this madness, as the Serbian forces engaged in permanent demographic engineering of the population in the region.”

“Besides, the very existence of the paramilitaries was out of question without the consent, encouragement, supply, and toleration of the authorities. When some paramilitary units forgot who set the rules of the game and started plundering the Serbian villages as well, they were quickly crushed by the regular forces.”

“Pašić further argued that due to the concentration of Serbian religious monuments in Metohija (southwestern and overwhelmingly demographically Albanian part of the present day Kosovo) this region had been a ‘Holy Land of the Serbian People…since time immemorial’ [oduvek] Karadžić, Njegoš and Garašanin all failed to make a ‘religious’ claim on any part of the present day Kosovo. Thus, it does appear that the ‘Holy Land of the Serbian People’ was a relatively recent invented tradition, probably formulated in the hope of mobilizing Christian solidarity from the Western Powers against the predominantly Muslim Albanians. The use of the ‘religious’ argument enables Pašić to claim for Serbia a part of the present day Kosovo that was clearly demographically Albanian.”

According to Tucović, the true inspiration and the model for the Serbian state were the successful European imperial powers:
“Serbian capitalists have opened their account of colonial murders and horrorsand now they can proudly join the capitalist company with the English, the Dutch, the French, the Germans, the Italians, and the Russians.”

“From 1914 to 1924, Serbian/Yugoslav troops repeatedly invaded parts of Albania”

“A 1921 report by a Serbian Radical Party member from Kosovo states that the local Serbs developed the ‘crazy idea’ that ‘Muslims will not be allowed to live in a Serbian state. On the basis of that idea, the local Serbs are committing various crimes against the Muslims.”

“The Yugoslav Army used artillery in the attacks on the rebel-held villages, the property of the families of the Albanian rebels was often confiscated by the state, and the Army routinely sent families of the rebels into concentration camps.”

“Dragiša Vasić, a moderate conservative and a Yugoslav military officer on duty in Albania and later secretary of the elite Serbian Cultural Club, saw the crimes committed in 1921 and described ‘poor Albania’ as ‘our shame’ in which Serbian soldiers ‘die defending plunderers and criminals.’ In 1921, Stojan Protić moderated his reported previous views and suggested that Kosovo and Sandžak should become one Muslim-majority province. Still, as Lapčević’s earlier statement aptly illustrates, it seems that the majority of the politically active Serbs were supportive of the colonial policy towards the Albanians.”
