Topic: Soft power or hard power?
For those of you who don't know the difference, allow me to explain. Soft power is power obtained by bonding (charisma, favors, empathizing shared values and flattery etc) and hard power is power obtained by more overt actions like having the ability to provide rewards (money, resources and weapons etc) or punishments (coercion and embargos etc).
Lately, there has been a hype in circles of political science that soft power is a highly valuable tool to increase in international relations, if not preferable to hard power. In fact, Chinese leaders have recently focused on increasing their own soft power, with investments in cultural exports and the 2008 Olympics. As would be expected, of course, many critics have argued that the costs of soft power are immense and the investments are less secure than strategies focused on hard power. I happen to agree with them. Soft power may have its uses, but it also has considerable limitations.
Machiavelli's "The Prince" couldn't do a better job explaining the limits of soft power. While he admits it's good to be loved and feared, between the two being feared is the best option. His reasoning is that while being loved may inspire the cooperation of others in periods of convenience, when you need their help in a time of adversity they will disappear. We see this every day. People may have superficial friendships by virtue of their likability, but when they really need their help their friends are gone. If, on the other hand, your friends are in some way dependent on you or you have a symbiotic relationship with them, then you can expect them to stand by you in a time of adversity. In the case of a ruler, they can expect the same if the adversity will cost their friends too, or if they are afraid of being punished for desertion. Incentives also work as an exchange for support. An unpaid army just isn't going to fight as well as paid one.
Ultimately, I think the soft power hype over rates its usefulness. It may be useful for breaking ice or establishing trust, but in the end hard power is more reliable. The bottom line is that statesman want to maximize their power, and if you can not offer them an incentive or threaten them with a punishment, you can not expect to reliably receive their cooperation. Hard power strategies may be more expensive, but they are also more reliable.
