If USA has riots and Trump is president ...and if i was Putin i would call my best buddy Xi Jinping and tell him to prepare the army and get ready for invasion...
Putin: - Xi it's time to visit America !
In the current conditions, I think Russia is a close friend of America, as evidenced by Putin's and Trump's agreement to stem the strengthening of the communist movement in the US. Trump asked for Russian help and Russia accepted the invitation of course with the privilege given by Trump to Russia regarding gas prices.
Racist issues and tensions that occur in the US were ridden by China through its proxy in Venezuela to be more soothing to break Trump's concentration. Trump currently has 3 main issues namely the pandemic, racist and Chinese issues. To win the second round, winning from China is the key. So Trump really concentrated starting from the possibility of restructuring at the pentagon to summon presidential advisors in the Reagent era.
If Trump is seen as megalomania, I think that at this time Trump is jealous of Putin and Xi Jing Ping who can perpetuate his rule for life. So Trump's goal is not just for the second period but to build the Trump dynasty. By perpetuating power, Trump's wealth will also increase and last forever.
But what will happend if the Democrats are winning the election. Then everything would be changed back to Obama levels maybe. I don't think the Democratic party, which attacked Trump many times for his close ties to Russia, will continue in the same fashion. Same for the pressure on China. We will likely see a change in the foreign policy of the USA if there will be a new president.
WW3 under the Democrats? Probably not.
