The United States is not immune from this. Even as our economy is growing and our troops have largely returned from Iraq and Afghanistan, we see in our debates about America’s role in the world a notion of strength that is defined by opposition to old enemies, perceived adversaries, a rising China, or a resurgent Russia; a revolutionary Iran, or an Islam that is incompatible with peace. We see an argument made that the only strength that matters for the United States is bellicose words and shows of military force; that cooperation and diplomacy will not work.
