When in 1925 Stalin fought the liquidationists, 
represented by the Trotskyites and Zinovievites, 
he pointed out that one of the dangerous 
characteristics of liquidationism was:

    . . . lack of confidence in the international 
    proletarian revolution, lack of confidence in 
    its victory; a sceptical attitude towards the 
    national-liberation movement in the colonies 
    and dependent countries . . . failure to 
    understand the elementary demand of 
    internationalism, by virtue of which the 
    victory of socialism in one country is not an 
    end in itself, but a means of developing and 
    supporting the revolution in other countries.

[MC5 adds: There are many
quotes like this where Mao links
confidence in the international revolution
with the confidence in the five sixths of the
population in the Third World. 
A moment's thought would reveal how important
this above quote from Mao quoting Stalin
is for small nations occupied by much
larger nations and comrades in big nations that are temporarily 
in a hard spot. German communists during World War II had to have
confidence in the "international proletariat revolution"
or they might have surrendered principled struggle.
The fact that they put up a fight and assisted the
Red Army invasion is much to be preferred to the French
path in May 1968 where the "communists" had numbers on their side and
gave up principles.]
