Wasn't the big distinction between Bukharin and Lenin's books on imperialism that B. used up all his ink insisting that despite appearances, nothing much had changed, while Lenin (presumably spurred on by B.'s failure to deal with the problem properly) wrote a book about the new stage in capitalist development, the point at which it had reversed its general course of development. Change is what needs to be explained, more than continuity

"it will always be characterised by imperialism and potential inter-imperialist rivalry. For that reason, it cannot shed 'race' or some analogue function in its political-ideological imaginary. Thirdly, since national states will be required to manage the labour market, and since national demographics do not always favour accumulation, some basis for admitting and deterring migrant labour will be required. That means forms of national and racial discrimination will persist. "
