The Military Writings of Leon Trotsky Volume 1, 1918 Two Roads "We have not forgotten, in the first place, that the Treaty of Brest-Litovsk meant the noose that was flung about our neck by the bourgeoisie and the SRs who were responsible for the offensive of June 18."
The Military Writings of Leon Trotsky, Volume 1, 1918 The Internal and External Tasks of the Soviet Power "Those who bear the guilt of the Brest-Litovsk peace are the Tsarist bureaucrats and diplomats who involved us in the dreadful war, squandering what the people had accumulated, robbing the people – they who kept the working masses in ignorance and slavery. On the other hand, no less guilt rests with the compromisers, the Kerenskys, Tseretelis and Chernovs"
The Military Writings of Leon Trotsky Volume 1, 1918 We Need an Army "the entire burden of recent events, above all, the Brest peace, has fallen tragically upon us only through the previous management of affairs by the Tsarist regime and, following it, by the regime of the petty-bourgeois compromisers".
