Momentum is on Ukraine’s side following two counter-offensives, around Kharkiv in the north-east, and Kherson in the south, that were conducted with a minimum of loss and a maximum of triumph. But those victories now raise the prospect of what would be much more humiliating Russian reverses in the Donbas and Crimea, territory seized by Vladimir Putin in 2014. Do you think that Ukraine attempt to retake Crimea can be supported by the western backers ?
