According to the National Intelligence Council of the Office of the Director of National Intelligence the US will no longer be the world's only superpower by 2030. In fact its role as a super power will be more likely a result of inertia than anything else.
According to the Report “Global Trends 2030: Alternative Worlds"(embedded below);
"In terms of the indices of overall power – GDP, population size, military spending and technological investment – Asia will surpass North America and Europe combined," the report concludes
"The United States’ relative economic decline vis-a-vis the rising states is inevitable and already occurring,but its future role in the international system is much harder to assess," it argues.The report projects that the United States will retain a unique role in the international system — because of its history and past leadership.
"The U.S. most likely will remain 'first among equals' among the other great powers, due to the legacy of its leadership role in the world and the dominant role it has played in international politics across the board in both hard and soft power," it argues.
"The replacement of the United States by another global power and erection of a new international order seems the least likely outcome in this time period,"Is this really inevitable or is just a result of "leading from behind." This is not the America people were voting for in November. Sadly it is the America they will get!
