Ukraine never chose to fight for Crimea that is why they lost it. Now they have chosen to fight and they are taking the fight to Russia. Your beloved Russia was planning to capture Kiev and Kharkiev and other main cities within a week but guess what Russia got its butt kicked and lost thousands of soldiers hundreds of Tanks, APC, Artillery, MRL and Air Defence destroyed. Dozens of Fighter Jets and Helicopters shot down. And now is scaling down its plans to concentrate on region in eastern Ukraine and even that it captures city then after few days ends up loosing it. Getting drones from Iran is clear indication how desperate Putin is becoming.
