Donald Tusk: "We are in a pre-war era and Europe has to be prepared to defend itself" Tusk urges compliance with the NATO commitment to dedicate 2% of the gross domestic product of each member country to defense. "We have to spend everything we can to buy equipment and ammunition for Ukraine, because we are living in the most critical moment since the end of World War II," he says.

If Ukraine loses, no one in Europe will be able to feel safe, he adds.
