The general view in SE Asia now is that Covfefe is a paper tiger; all he cares about is selling more natural gas to the region. He talks tough, but there's no substance behind the words. American diplomacy is completely paralyzed. As America withdraws, China becomes the dominant player both economically and politically, especially where bilateral relationships are concerned. On the N.Korea issue, America is expected to make serious concessions to China if Covfefe wants any meaningful sanctions enforced.

Also, after Covfefe posted the video where he beats up CNN, talking about advantages of American Democracy over Asian Authoritarianism makes no sense. People just roll their eyes and chuckle.
