Washington is trying to reassure its Ukrainian ally after leaking secret documents. The documents question the ability of the Ukrainian army to carry out the counter-offensive.

U.S. intelligence is concerned about "persistent deficiencies in the training of men and ammunition reserves" The Americans are also concerned, says the France-Press Agency, about the worrying state of Ukrainian air defenses that could run out of ammunition by the end of May. The document concludes that Ukrainians could achieve only "modest territorial gains" against the Russians – a far cry from the successes of last autumn.
