Fine...
You can criticize the American hegemon and unipolarity all you want, although I doubt you understand the proper context of unipolarity in the first place, but the question was...
I am a very easy going guy, not many things in life bothers me. But in the very short list of thing that do bothers me, it is whiners/critics who can spare no energy whining about the current shituation but offers no solutions.
Unipolarity -- of the geopolitical kind -- is the
OVERWHELMING preponderance of power and influence.
What is the meaning of preponderance ?
the quality or fact of being greater in number, quantity, or importance.
The preponderance of US power and influence in the four critical areas of economic, military, political, and technological, is so overwhelming that the erasure of that level preponderance can only be achieved by the utter military defeat of the US. In other words, you cannot simply refuse to use the dollar, or dump US Treasury, or us sanctions, or most laughably politically isolate the US, even in the hope of bringing US down.
Do you know of the old saying: 'The bigger they are, the harder they fall' ?
It is very easy to say that about the US. But the reality is that whenever someone say that about US, it is more to satisfy their own private jealousy of US than it is about understanding international politics.
Yes, the bigger something is, the harder it fall. But the problem is that the bigger something is, the greater the effort that is required to begin its fall. It is called 'institutional inertia'. Do you understand ? No one forces anyone to watch the dreck that comes out of Hollywood, but do you seriously think Bollywood is a viable replacement ? McDonald's is a greater success in India than the plethora of Indian restaurants in the US.
Currently, the US have a preponderance of power, in all four critical areas, to a degree that neither the Roman Empire nor Great Britain attained. And look how long it took them to fall -- hundreds of yrs.
