British Prime Minister Keir Starmer's visit reflects Europe's concern over Trump's push to end the war in Ukraine and concede too much to Russian President Vladimir Putin.

Despite talk of allowing U.S. companies access to its resources, Russian oil will remain an unattractive investment given the political risk.

Claims of a peace deal between Ukraine and Russia actually repeat key parts of a proposed U.S.-Ukraine agreement for sharing revenue from Ukraine's natural assets, including minerals. This agreement is not a peace deal but would bring Americans to Ukraine and give the U.S. a vested interest in peace in the country.
