[HIGHLIGHTS] The alarming warning from a former British chancellor if Trump governs again: "It is not just Ukraine that is being threatened but all of Europe"

Vladimir Putin says Russia is ready for a nuclear war over Ukraine. Russia has the world's largest nuclear arsenal with 5,580 nuclear warheads, according to the Federation of American Scientists.

Trump's irresponsibility leaves Britain and France with vital roles in protecting the continent if Ukraine loses the war. “Europe, for the first time since 1948, may not be protected by the United States from the threat of nuclear war or blackmail from the Kremlin,” Malcom Rifkind said.
