Trump has turned on Zelensky and struck a diesel supply deal with Russia — bad news for Ukraine, mixed news for American drivers and farmers.

• Trump says Ukraine needs a new leader after Zelensky ignored his warning not to hit Russian refineries.
• Russia will ship millions of tons of diesel to the US, with Treasury shielding the deliveries from sanctions.
• The motive is money: diesel is over $6 nationwide and above $8 in California, and diesel moves everything, so its price feeds into all other prices.
• Critics point out the US is already the world's biggest diesel exporter and could have bought from Saudi Arabia, India or South Korea instead of Russia.
• The deal may only cover days of American demand, and Russia struck a Ukrainian power plant right after an energy ceasefire was announced.

Outlook: Expect the deal to be sold hard before the November 3rd midterms, while Zelensky's offer of elections after a 60-day ceasefire goes nowhere.
