A former Ukrainian defense minister has shared his perspective on the conflict with Russia. Mykhailo Fedorov, who is credited with developing Ukraine's modern war strategy, believes the country is engaged in a technological war with Russia. Fedorov, who was ousted from his position last month, had been working to utilize drones and robots to counter a larger adversary.

His departure was reportedly due to a feud with a top general. Further details on Fedorov's interview and the situation in Ukraine are available from CBS News.
