Imagine some foreign nation sent 100 missiles into Washington D.C.
You can imagine this because Hollywood has trained you to imagine it.
Imagine that for weeks or months prior to this attack, the foreign nation’s government and public debated whether to do it.
You can imagine this because you live in the one nation on earth where such debates happen, or because you have heard about the sorts of things that go on in the United States.
Now imagine that the primary excuse for the attack settled on in the debate in the distant foreign capital was this: it would be punishment for the U.S. government’s use of and possession of banned weapons: depleted uranium, white phosphorous, napalm, cluster bombs, etc.
You may be able to imagine that, depending on what you know about events in the world and how good you are at playing role reversal.
