Let’s face it, US has been great partly and significant so, because the world has viewed her as a force for good – well meaning. If or when that the US gives the world reason to believe that they no longer represent that position, then that would be watershed moment!
This is to say, if Trump were to continue on the trajectory he is on right now – sliding all the way - with arrogance, bullying, threatening to dishonour treaties, humiliating allies like Australia, threatening war on Iran off hand – no diplomacy, not promoting of confidence/stability/predictability - in regard to if the world can bank on US – in terms of its actions utterances and general behaviour – then that point may be deemed to have arrived.
If that be so, her influence around the globe would dwindle considerably including such measures as - rejecting US Dollar as the world reserve currency, among other backlash options.
But the US consists of institutions such as congress, state governments, Federal Judicial system – all of which would not ordinarily let matters slide to such levels. Trump would be tossed out like a hot potato.
