I’ll try this in long form. In my defense this form lends itself to hip-shot returns to short comments and I apologize to those who want more meat on the bone. So, on to business…
In the closing days of WWII FDR made the ultimate realpolitik move when he froze Churchill out at the Yalta talks believing that the Soviet Union and the U.S. were all that was needed to bring peace to the world. Churchill was the old world, the Western Europe of colonialism and greed. So, the globe was divided and peace was to rule the land. FDR saw the end of the war as the moment the globe would shift from Realism to Liberalism Of course, FDR died and Stalin was already planning on skipping any deals made there. The next shoe fell when the world let the nuclear monster out of the box. The concept of mutual defense combined with the idea of mutually assured destruction meant that Neoliberalism (the diplomatic actions of liberalism) was born a terrified child.
Neoliberalism identifies the one main problem in international politics as war. To solve this, it proposes three solutions. The first is democracy: True liberals argue that democratic states are more peaceful with all other states and never go to war against other democracies. This is the argument of Democratic Peace Theory. The main reason for this is that states’ leaders are accountable and they fear that they may not be re-elected if they go to war. The second solution is economic interdependence. Liberals note that international trade binds states together, and the interests of a state become those of other states. Thus, war appears too costly for states and they prefer to cooperate. The third legislator the creation of international institutions to enhance cooperation between states and therefore make war less likely. Neoliberal Institutionalism particularly leans on this solution: it argues that international institutions promote cooperation and limit the effects of anarchy. These three legs are the supporting structure of soft power theory - but they don’t explain why it doesn’t work that well in the modern world.
I think all here would agree that power is simply the ability to get others to do what you want, and that requires a set of tools - kind of like the “guns and butter” concept. Some of these are tools of coercion or payment, or hard power, and some are tools of attraction, or soft power. For individuals, charisma, vision, and communication are key soft-power skills; for nations, soft power should be embodied in their culture, values, and legitimate policies…but in truth it isn’t, at least for the West. The best recent example is what happened in Afghanistan. First, Bill Clinton tried a soft power approach by asking the Taliban to boot Bin Laden and his bad kids out of Afghanistan - it didn’t work because what we mistakenly call “liberalism” here isn’t actual liberalism - all Clinton could offer was some cash and that wasn’t enough for the Taliban to change. So, 9/11 happens and we try the hard power approach. It worked for a bit but the West needed to have Afghanistan join the peace loving global community, so we return to soft power. So, why didn’t it work? Simple…liberalism no longer means what it is supposed to mean. Western “guilt” requires that old world liberalism (a critical concept) be cast aside with neoliberal ideas that eschew the very freedom we were supposed to bring. Why didn’t we simply establish an Afghan government and hand them a Constitution (adapted to their culture)? Because that is what “colonizers” do…besides…what do we know? We must atone for our evil past! And so it goes, eternal “small wars” and billions spent on vanity projects when we should be using our soft power to advance genuine, traditional, liberal ideas, like democracy. That is Smart Power.
One can argue that soft power is preferable to hard because it gives more freedom to the person who is its object, but keep in mind that soft power is not good per se; it has to be put to good purpose., not party agendas. Remember, the ability to attract others has been possessed by some evil people: Hitler, Stalin, Mao, and BinLaden to name a few. Teddy Roosevelt was the epitome of smart power: the combination of soft and hard power in the right mix in the appropriate context. The problems facing America and the world today are going to need lots of smart power, and leaders who want to understand it could do worse than to study Teddy Roosevelt. He was acutely alert to the use of hard power—look at his fondness for the military. But he was also aware of the importance of soft power. Roosevelt’s chief motivation in negotiating crucial treaties such as the Portsmouth Treaty of 1905, which ended the war between Russia and Japan, was to make the United States more appealing. When he sent the Great White Fleet, the new American navy, on a tour around the world, he wanted both to display the country’s new military power and to advertise America as a force for good (sounds like a recruiting commercial, yes?) In effect, he used a hard-power tool—the navy—as a soft-power symbol. We lack this skill today because we have entered a period where we can’t express the absolute superiority of our ideas because of a long distant past and the neoliberal idea that any expression of power must atone for what was done.
Last point, I do not believe that Trump is the “father of new smart power,” probably the opposite. He is clearly a hard power, realpolitik guy, but maybe we need that mess and breakage to reset to a better way. Most of the above is drawn from my reading of Robert Nye (and he wouldn’t agree some of it!).
