Johan Galtung see 2020 as the end of the US Empire

From http://geraldcelentechannel.blogspot.com/2010/06/johan-galtung-fall-of-us-empire-and.html

... I made a comparative study of quite a lot of declines of empires. I'm a little bit of an expert on that, actually. And there are certain factors that are similar. They rise and decline more quickly now. Of course, the two Roman empires, the Western and the Eastern, lasted longer. Now it’s quicker. The US started, I would say, in 1898, walking into the shoes of the dying or dead Spanish empire. And we are now dealing with a phenomenon which is about 110, 112 years old. And as I told you, I put the upper limit at 2020.
