The political adjective Wilsonian is good for describing a policy or idea that's similar to those of the twenty-eighth US president, Woodrow Wilson.
You can talk about a Wilsonian, a follower or scholar of Woodrow Wilson — a Wilsonian, for example, might write a biography of the former president. It's even more common to describe a particular kind of US foreign policy as Wilsonian. A Wilsonian philosophy, with a stated eventual goal of world peace, includes ideas such as the spread of democracy and capitalism and policies of intervening in other countries' conflicts. Former president Bill Clinton is sometimes described as having a Wilsonian ideology.
