I have said it before and I will say it again.
It is not in the interest of the US that this war finishes. A stalemate guarantees continued weapons sales much longer that peace.
Currently the US is getting
- raised income via defence and energy contracts (incl. Oil & Gas) &
- prolonged economic disadvantage to a competitor nation via sanctions.
“Left the US” could also have been written as “Returned to his country of birth”, but that doesn’t play to the fake arms race vibes.
