Donald Tusk, prime minister of Poland, said the country is preparing for different situations and that the coming months could be “vital” in the face of a Russian threat. He made the remarks after reports that say Moscow may plan an armed provocation in Poland to test NATO’s resolve. The reports cite US intelligence warnings to Warsaw. Tusk said he does not intend to scare anyone, but that changes in the nature of war cannot be ignored. He added that concerns are especially felt in the Baltic states, and that Poland, with help from its allies’ intelligence services, is pursuing the threats.
