America thinks it's still the world's super power because they got guns. Trump forgets that it doesn't take power to fall, but a mind that can lead, he lacks strategy in execution of his leadership and he thinks too highly of himself. He doesn't realize that China is also rising, Asia might be on the lead in a couple of years, it's just a matter of time.
There's a saying that goes "Anyone would loose sight of creeping shadows while basking in the bright light."
The US has been at the center-stage for far too long that it's made them ignorant & arrogant (Look at the tide pod and hot coil challenge currently trending)
Their President is an accurate representation of who the world thinks they are. With all the crap he's pulled (So far) any other president would have been impeached 10 times over, yet he's still there.
Just like the Greek, Roman & Egyptian empires.., everything has to come to an end at some point
