Pentagon Papers reveal Ukraine stalemate compared to Vietnam, NATO responds.

Daniel Ellsberg, the man behind the Pentagon Papers leak, has said that the war between Russia and Ukraine is at a "stalemate," drawing similarities to the Vietnam War. Ellsberg said the leaks of NATO intelligence on the war in Ukraine offer a look into the fighting that officials have not provided publicly. He cited Russia's nuclear capabilities as one of the reasons the conflicts are connected, with a world power involved that has nuclear weapons.
