I learned most of the revolutionary history from Hasegawa's The February Revolution, Petrograd, 1917. The End of the Tsarist Regime and the Birth of Dual Power (2017) and Lowe's Mastering Twentieth Century Russian History (2002). The first book is great if you enjoy reading scenic accounts of the uprising, the second is notable for comparing the soviet, liberal, revisionist, and contemporary historians' views side by side.
My understanding is that there were three components to war attitudes: whether to continue the war, to pursue what war goal, and, of course, the rationale behind the previous two.
Defeatism: Lose the war. The defeat would spark a revolution for a socialist regime. Once Lenin's solitary view, later gained popularity as war weariness mounted and Lenin himself returned to Russia.
Defencism: Defend Mother Russia, despite whatever regime is reigning. Plekhanov's view.
Internationalism 1: End the war, not through military victories but by proletariats across borders jointly disobeying their autocratic / bourgeoise oppressors. The war was imperialist in nature, and they wanted no annexations and indemnities. Martov's pre-Frebruary view.
Internationalism 2 / Revolutionary War View: Continue the war. War destabilizes the belligerents and sparks socialist uprisings. When proletariats took power, the war would end spontaneously. Bukharin's view.
Revolutionary Defencism: Continue the war to protect the revolution. Some also wanted to recapture lost territories. Dominant within the Menshevik after February.
Social Patriotism: Nationalism with the socialism influence. Most socialist workers had this view early in 1914 (?)
Expansionism: Win the war and take the spoil, which meant on top of recapturing lost / Slavic territories, capturing enemy territory was also important. Miliukov's view.
Notwithstanding, these attitudes might not have been as meaningful labels to individuals among the masses as they were to the party leaders. Likely, many Bolshevik supporters might have cared more about bread and war casualty than about defeatism.
