#1 thing would probably be consistent foreign policy. In the case of the NATO states, our supposed revulsion against fascists, feudalists, theocrats, warlords, etc., would be far more credible if we weren't openly and proudly trading with and propping up the cartoonishly despotic and backward Wahhabi regimes in the Gulf.
And that's without even mentioning NATO's covert ops against many MENA secularists/Westernizers early in the Cold War over economic nationalization and accepting trade with the Warsaw Pact.
Just make it a priority to consistently support democracies and secularists, economically shun totalitarians and fundies. Don't let petty politics between private interests or global powerblocs get in the way of that, live up to the UN charter.
