As Lunacharsky once pointed out, Trotsky never did anything without looking in the mirror of history. Or, more fully, in Revolutionary Silhouettes:

Trotsky is undoubtedly often prone to step back and watch himself. Trotsky treasures his historical role and would probably be ready to make any personal sacrifice, not excluding the greatest sacrifice of all – that of his life – in order to go down in human memory surrounded by the aureole of a genuine revolutionary leader.
