I don't see any connection to the US in the screenshot. But evidence of cooperation/unification of N & S Koreas is good news. Plus if Russia has additional Pacific Ocean access it may reduce pressure for ports on its Western front.
Not that important, but the math on the gold doesn't seem to work. At today's spot price of $1230/ounce $133 billion gold value would be 3379 tons. ($1230162000=$39,360,000/ton). Maximum cargo load Donskoi had previously carried was 1,625 long tons or 1,849 tons. https://www.revolvy.com/page/Russian-cruiser-Dmitrii-Donskoi Still a lot of gold possibly on the ship.
