Frustration is growing amid increasing signs US could wash its hands of Ukraine, but some observers counsel patience

Gen Keith Kellogg, Donald Trump’s somewhat estranged special envoy on Ukraine, is said by some US diplomats to like to joke that the president did indeed say he would solve the Ukraine crisis in 24 hours, he just never specified which 24 hours.

Dark humour may be all that is left to Europeans as they absorb not just Trump’s refusal to impose the promised “bone-crushing sanctions” over Russia’s rejection of a 30-day ceasefire but also the increasing signs that the administration will wash its hands of Ukraine and instead focus on forging a new economic partnership with Russia.
