Yeah, the idea is that we wanted to move focus from might make right to deterrance and international law. It's why the UN charter prohibits agressive war but allow self defense, and why the US renamed its departement of war to department of defense in 1947.

So yeah, sure, in the current attitude and action that are very much "hey let's go back to that great time where we openly agreed war of conquest are a good thing" they have it makes sense.
