No, it's not frustrating; it's scary as shit.
I was going to leave this below, but then Anderson Cooper noticed it. Here's what happened, per Vox:
“After listening for 10 minutes, I realized it’s not so easy,” the president told the Journal. “I felt pretty strongly that they had a tremendous power [over] North Korea. ... But it’s not what you would think.”
Four quick observations about this:
Trump thought China could fix North Korea until the Chinese president politely informed him that North Korea is in fact complicated.
Trump seems to have required the leader of China to explain basic facts to him that he could have Googled, or at least asked one of the many US government North Korea experts about.
Trump came to a profound realization about one of the most dangerous conflicts on earth after a 10-minute conversation.
Trump is getting his information about East Asian affairs from the leader of America’s largest rival in the region.
But then, humankind cannot bear very much reality.
