Everybody involved in the situation which of course includes Americans but also includes her Allies, after all, a workable solution will require their cooperation.
That's no good if they have no assets to cooperate with.
Every nation has some "assets" that could be used to re-configure the workload of maintaining global stability so that the U.S. doesn't have to shoulder the lion's share of the burden like it's had to for the last 70 odd years.
IMHO Trump needs to articulate a clear and coherent strategy that indicates what the expectations are so that he can garner both domestic support and the support of the nations involved. We've had to be the "global cop" since WW II and if we don't want to keep having to do that the U.S. is going to have to provide the leadership and sell the strategy to change it.
