If the fighting in Ukraine is ended with a peace deal, Ukrainian troops could be sent to help defend the EU's eastern borders against Russia, Defense Commissioner Andrius Kubilius said Monday. "It would be good that a battle-tested Ukraine army, after peace has been established in Ukraine, would be ready to be present in all the countries of our frontier region, starting from the Baltic region and in Lithuania, next to German brigade and the rotating U.S. battalions," Kubilius said in Vilnius.
