During an official visit to Vietnam on Friday, Russian Security Council Deputy Chair (and former President) Dmitry Medvedev told journalists that the “military conflict” in Ukraine will be “long-lasting.”

“This will be going on for decades, probably. It’s our new reality, the new conditions of life,” Medvedev said. He added that if Ukraine doesn’t undergo a change of government, there will be “three years of a ceasefire, two years of conflict, and it will all repeat.”

On May 18, Politico reported that U.S. officials are considering the possibility that the war in Ukraine could become a frozen conflict that lasts “many years,” comparing it to the Korean War.
