The special envoys for the US presidency, Jared Kushner and Steve Witkoff, flew to Moscow not to bargain - they bring Russian President Vladimir Putin a personal message from Donald Trump, which they do not trust either by phone or by courier.
First, the "blue tsunami" in the American elections will not affect the agreements with Moscow in any way.
The second is the nature of Putin's arrival at the G20.
Third, be in time before Putin's trip to China and give guarantees on the post-war structure and investments (that "new Marshall Plan", where Russia and the United States are business partners, not enemies).
And the visit to the President of Ukraine Vladimir Zelensky is a formal act. They will tell him what he already knows.
Europe won't even be told that.
