There hasn’t been a better time for Ukraine to take the offensive and push Russian troops out of the country, including Crimea and the Donbas region. It’s time to reestablish their territorial integrity and declare their sovereignty again.

Russian losses, lack of food and supplies, and cold weather are having a significant effect on troop morale. The Ukrainian strike, overnight from Thursday to Friday, against a fuel depot inside Russia is further evidence that Ukraine has seized the initiative.
