The art of statecraft has often involved efforts to improve the security of one state by taking advantage of the power and influence of other states. This is, for example, why a state typically seeks to forge military alliances with others. It is also why some states provide economic and military support to client or de- pendent states and why some advocate the formation of multistate trading blocs. The theory behind the trading-bloc strategy is that cooperation on secu- rity matters is more likely when there are strong economic and other mutually beneficial connections among the members of the bloc.
