Russia's war against Ukraine could take years, NATO Secretary General Jens Stoltenberg told the German newspaper Bild am Sonntag, adding that the supply of modern weapons to Ukrainian troops would increase the chances of the country's liberation..

British Prime Minister Boris Johnson made a similar statement on the pages of the Sunday Times..

" We must not stop supporting Ukraine," "

A NATO summit in Madrid at the end of June is expected to agree on an aid package for Ukraine to help the country transition from old Soviet-era weapons to NATO standard equipment, Stoltenberg said earlier this week..

Johnson urges allies not to relax and prepare for a long war until the complete victory of Ukraine. He considers it necessary to continue to provide Ukraine with weapons, equipment, ammunition and training so that it builds up its combat potential..
