Trump is publicly blaming Ukraine for prolonging the war, a bad sign for Kyiv's standing in Washington and a warning for diesel supply worldwide.

• Trump says the war could have been settled several times and Ukraine chose not to.
• He says the U.S. gave Ukraine a free hand against Russia with one condition: leave the refineries alone.
• Ukraine struck Russian fuel production anyway, and Russia supplies a big share of the world's diesel.
• Higher diesel costs hit farmers, ranchers, and anyone moving goods by truck.
• The bigger problem for Kyiv is political: it defied the one line drawn by the country whose help it needs most.

Outlook: Expect more pressure on Ukraine from Washington and tighter diesel supply if refinery strikes continue.
