As world leaders met at this week's NATO summit in the Netherlands, Christiane's exclusive interview with Canadian Prime Minister Mark Carney. The two discussed the fallout from the Israel-Iran conflict, a resolution in the war in Gaza, Canada-U.S. relations, Trump's demand NATO allies boost defense spending by 5% and whether Ukraine can still count on U.S. support. Then, former White House Arms Control Coordinator, Gary Samore talks to Christiane about whether Iran will continue to pursue its nuclear program and how the origins of Iran's nuclear ambitions began. From her archives this week, Christiane's rare 2007 visit to Iran's nuclear plant in Isfahan, one of the three targets of the recent attacks by the U.S. and Israel.  And finally, Christiane pays tribute to the wonderful war reporter, Rod Nordland, who passed away earlier this week after a six-year battle with an aggressive form of brain cancer.
