Since the end of the Cold War, the US has been the only true global superpower, with US policymakers intervening freely anywhere around the world where they feel there are vital political or economic interests to be protected. Most of the time US policymakers seem to act without a clear strategy at hand and surely without feeling the need to accept responsibility for the consequences of their actions. Such is the case, for instance, with the invasion of Iraq and the war in Afghanistan. US policymakers also seem to be clueless about what to do with regard to several "hot spots" around the world, such as Libya and Syria, and it is rather clear that the US no longer has a coherent Middle East policy.
What type of a global power is this?
