Recent news has made it plain that President Trump intends on going through with his much discussed plan of implementing tariffs on many sources of steel and aluminum imports to the US. This seem as good a time as any to ask a question that begs for evidence: Are trade wars good, and who benefits?

There is good reporting out there that analyzes the likely impact of this particular steel tariff, so feel free to find it and use it in your own argument (there are figures the administration has produced and figures that other studies have produced using the same source material). There are also plenty of other tariffs out there throughout history that have been studied and discussed. Because these sources can sometimes conflict, please be aware that your choice of what sources to use may need to be justified.

On the heels of President Trump pulling out of talks with North Korea over nuclear disarmament in the Korean peninsula, the United States' pending withdrawal from the Paris agreement (coming soon! ... the day after the next presidential election), and the United States' unilateral withdrawal from the Iran nuclear agreement, combined with ongoing Russian and Iranian leadership in resolving the Syrian civil war and Chinese leadership in talks with North Korea, we seem to be heading toward an ambiguous point in international geopolitics.

So this question is simple and nasty: Is the United States on its way to losing its status as the unquestioned dominant world power in the international order?

If it is on its way off the top of the food chain, who will challenge it? Are we returning to a cold war-style era or are the lines shifting and different? If the United States is not on its way to losing its dominant status, how might it maintain its footing in a world that seems increasingly disillusioned with it?
