You can generalise with a lot of small cases, if you feel so inclined.
For example, in an "evaluate the effectivenes of legal and non-legal measures in achieving world order" question, you can say:
One legal measure is the ICC, established by the Rome Statute (1998). To date, the US has still not signed the Rome Statute because it fears that its troops could be prosecuted against. In theory it is an effective meausre blah blah coz its binding. However, it still hasn't prosecuted an individual and its aiming to prosecute Slobodan Milosevic for Crimes Against Humanity.
The EU is also a great example for everything surround World Order coz it has the fundamental ideas of World Order in place.
Does that help at all? Good luck...
