(i) The US power lies in the overwhelming superiority of its military power. American military dominance today is both absolute and relative. In absolute terms, the US today has military capabilities that can reach any point on the planet accurately, lethally and in real time, thereby crippling the adversary while its own forces are sheltered to the maximum extent possible from the dangers of war.
(ii) No other power today can remotely match them. The US today spends more on its military capability than the next 12 powers combined. Further more, a large chunk of the Pentagon’s budget goes into military research and development, or, in other words, technology. Thus, the military dominance of the US is not just based on higher military spending, but on a qualitative gap, a technological chasm that no other power can at present conceivably span.
