Brute force is not sufficient to maintain global security. Just as one cannot simply strike a stone repeatedly and expect to replicate Michelangelo’s David, one cannot simply produce more tanks and train more soldiers and expect to resolve the complex problems that create modern global threats. The US has failed to establish a stable and safe environment in Iraq and Afghanistan despite almost 10 years of occupation. The Pro’s arguments point to failed or misguided intervention in Vietnam, Chile, Somalia, Lebanon, Grenada, Libya, and Haiti. These examples demonstrate that the US is not receiving much benefit from the vast resources it puts into its military. The US is only one country, and thus does not have the capability to view global conflicts from an international perspective. The world would be better served by greater investment in international military entities, such as NATO or UN peacekeepers. An international response to global conflict has greater perceived legitimacy than a unilateral response by one nation; perceived legitimacy reduces backlash from groups that feel victimized. Thus US military intervention is not a very effective means of attaining sustainable peace.
