" ... The world paused to witness the mighty clash between the two most powerful men on Earth and the painful confrontation of the declining superpower with its rising challenger..."

OH PLEASE !
They had a nice dinner together and discussed world affairs, trade and perhaps Syria, the weather and the price of oil ....

The USA is not a declining superpower - both in terms of technology and economic capacity. Of course that would not result in click bait paragraphs. The current political situation may be a circus and thereby entertaining, but is not the ultimate reality underneath. There was no "mighty clash" - really !
