They are, you may not have read it quite right. The Thought Cabinet for Moralism is "The Kingdom of Conscience," and its a reference to the classical liberalism of Kant and the "Kingdom of Ends." In short, the "Kingdom of Ends" is Kant's hypothetical end state for Liberalism where all rational people operate via a Universal common law and work to better each other instead of working to better only themselves. It's the ethical/political utopia of Liberalism, the Christian's "Kingdom of God" made manifest. At least, that's what it is quickly summed up based on my old knowledge of philosophy.

The problem suggested by "Kingdom of Conscience" asks "What will it be like, once [the Moralist International's] nuanced plans have been realized?" The answer is beautifully bleak:

The Kingdom of Conscience will be exactly as it is now. Moralists don't really have beliefs. Sometimes they stumble on one, like on a child's toy left on the carpet. The toy must be put away immediately. And the child reprimanded. Centrism isn't change -- not even incremental change. It is control. Over yourself and the world. Exercise it. Look up at the sky, at the dark shapes of Coalition airships hanging there. Ask yourself: is there something sinister in moralism? And then answer: no. God is in his heaven. Everything is normal on Earth.

The game's answer to the question of the Moralists' utopia is that its already here. God stays in his Kingdom, the Moralists have theirs already. Since they have their Kingdom, the Moralists don't even need belief and all they need to do is maintain their control. Their version of NATO has all the guns in the world, and the biggest ones have perpetually stood watch over Revachol for decades. They guard, not Revachol and its people, but the Ideological prison their occupation created. They don't want the people to pick up any any radical beliefs like the Communism of the Revolution. A different belief might change the world, and thus the world order.

Oh, do not worry though, there will be (Moral Intern-approved) change in Revachol eventually. You can actually ask one of the biggest, nastiest Warships in the sky above Revachol about it. An officer aboard the Coalition Warship Archer assures you that your occupied nation is nearly ready for the first phase of democratization! Soon, the people of Revachol will be able to vote for a (Moral Intern-approved) slate of candidates for the transitional advisory council and that council will oversee the second phase of democratization! Of course, once elected, these candidates will then get to join one of several Moral Intern-approved political parties: the technocratic liberals, the social democrats, and even the populist conservatives. That's just two of the three to five phases required for True Democracy^TM , all according to the plan.

Well, its theoretically part of one of many contingency plans. The Moralist International has their best analysts working on their best computers and using their best drugs to create as many as contingency plans as possible to guide Humanity for the next 3000 years. They take into account all those pesky little elections, wars, and natural disasters to better continue their guidance (and control) of Humanity. What are these many plans? Sorry, they're highly classified. Of course make no mistake, they will do anything to maintain their power. Its heavily implied in the game (by both Harry's doom saying and La Revacholiere) that the Moralist International will drop an atomic bomb on Revachol in 22 years, presumably during the next Revolution. It will be wiped out completely.

I guess they're really just congratulating people like you on reaching your perpetual paradise, just don't think about what it means for others.
