Given the extreme Russophobia currently being exhibited by the Democrats and a huge range of media figures in response to Trump's alleged conflicts of interest, I hardly think the current context signals a long term strategic de-escalation of tensions with Russia.
But either way, the US is set to become a more volatile, more dangerous participant in global geopolitics as its economic power declines and it increasingly falls back on sabre-rattling.
"Ordinary people" in industrialising countries, perhaps including Russia though its export economy still centres on primary resources, will be better off through no action of the USA (other than buying the goods they help to produce) but the risks of unpredictable US actions will increase, contra the historical, stable US strategic stranglehold on various hotspots.
For Australians, the contention over the South China Sea is already getting interesting, with both of our major parties strongly backing an increasingly fragile and belligerent US as it attempts to stir up FUD about the regional expansion of PRC influence while maintaining its own, very heavily armed position, which of course includes its control of Taiwanese ICBM placements trained on the Chinese mainland.
