Each of these countries that we have expended blood and treasure to liberate should be required to include in their new constitutions the same guarantees of liberty that we have in ours. Anything else should be a nonstarter.
My thinking is, why not just Xerox our Constitution and hand it to all concerned for signatures? We can place some people there to explain it to them, if necessary.
It's worked for us, and the principles have worked wherever they've been tried.
In fact, If I recall correctly, that's pretty much what McCarthur did with Japan after WWII, with some small mods to keep them from developing a military, and preserving the Emperor as a figurehead.
