the phrase having explored all other options is clear, it means the Americans will do the right thing after they have done all the wrong things and tried to make them work. When they cannot make the wrong things work then the will finally, grudgingly, do the right thing. If they can make the wrong thing work they will stick with that. The idea of the ironic viewpoint is of course that some other countries have a larger bag of wrong things they might be willing to try. It's a pretty common comedic trope in English writing to say that someone will do right only after doing wrong. So, the high dudgeon in response is rather missing the point.
