Former CIA Director David Petraeus on Sunday called Mariupol “a Ukrainian Alamo” that ultimately “looks as if it’s going to have to collapse.”

“It’s fighting to the last defender and pinning down multiple Russian battalions, and doing so very heroically,” he said on ABC’s “This Week” of Ukrainian defenders fighting Russian forces. “But ultimately it looks as if it’s going to have to collapse. It’s going to be taken.”

“And when it does, that is a moment of some peril for Ukraine because now that port can be used by the Russians,” the retired Army general added.
