Dictatorships, semi-democracies and authoritarian states act out of cynical self-interest. Both internally and externally. They are corrupt governments, with the resulting low trust societies. Idealism, human rights and the common good are impulses of policy that are entirely alien to them, and so they can't believe these are main drivers of Western democracies.
Add in that whole brew of Western hypocrisy, self-interest, cynicism, internal policial interests, and downright mistakes, and it becomes impossible to convince anyone that humanitarianism is one of the main drivers of Western policy.
