Donald Tusk told parliament on Friday that if Russia took control of parts of Ukraine, then Poland would find itself in a “difficult geographical situation.”

He said: “We are preparing large-scale military training for every adult man in Poland. Our goal is to finalize the plan by year’s end to ensure a well-trained reserve force ready for potential threats.

“If Ukraine loses the war, or if it accepts the terms of peace, armistice, or capitulation in such a way that weakens its sovereignty and makes it easier for Putin to gain control over Ukraine, then without a doubt—and we will all agree on this—Poland will find itself in a much more difficult geopolitical situation.”

Talking to reporters, Tusk later clarified that he was not announcing a resumption of basic military service.

“If I were proposing a return to basic military service, I would say so. We have several models. One of the most appreciated ones is the Swiss model,” he said, adding that in the latter system training is “not compulsory, but there are incentives that cause men to opt for annual training.”
