Unfeasible-captures?

In this paper, I wish to cast a doubt as to whether the standard conception of the problem of DH—the recognition that, in certain inescapable and tragic circumstances an innocent course of action is unfeasible—fully captures Machiavelli's message and its terrifying implications.

here, in certain inescapable and tragic circumstances an innocent course of action is unfeasible means that ’that‘ statement is not able to capture Machiavelli’s message? Do I understand right?
