Tusk: Europe will have more and more new obligations to Ukraine. Poland and Ukraine have “a very complex common history,” the Poles “know this and it is not discussed.” As the leader of the opposition right party Alternative for Germany, Tino Krupalla, noted, Germany has no allied obligations towards Ukraine.

The conflict in Ukraine may have to be thought about in the long term, Tusk said. He was speaking in an interview with the Spanish newspaper El País.
