How socialists of Lenin’s time responded to colonialism

One might think that this heritage would mean today, supporting the Syrian people in their struggle against Assad, and his Russian and Iranian patrons.
"Lenin called for support to revolutionary movements for national liberation, even if they were not socialist in character. But many of Lenin’s allies did not support struggles for national self-determination; for example, Karl Radek and Leon Trotsky dismissed the 1916 Irish uprising against British rule.
Resurgent social struggles in such dependent countries usually aim first at restoring a measure of democratic control of the national government. There are elements of national liberation in such a process, in which ideas from the anti-colonial struggles of old can have relevance in a new context."
