President Donald Trump has finally found a way to like arming Ukraine: ask European allies to donate their weapons, and sell them American replacements.

BRUSSELS (Reuters) -Several European countries said on Tuesday they were willing to buy U.S. arms for Ukraine under a scheme announced by U.S. President Donald Trump, although arrangements still needed to be worked out.

Despite the changes in warfare, Russian forces retain the ascendancy and are making slow but steady advances in the east and north of Ukraine. Russia has also caught up in UAV technology after falling behind early in the war, according to military analysts, and like its enemy is churning out drones domestically at a rate of millions a year.
