Hello everyone and welcome to the Ammanpur Hour.

Here's where we're headed this week.

Are America's allies getting cold feet about a friendship that's lasted since World War II?

I ask a former leader of Canada's Liberal Party about that and how Prime Minister

Mark Carney could be leading the breakup. We cannot rely on the United States, period. Then, a true

story of heroism and disaster on the edge of space 40 years since the U.S. Space Shuttle Challenger

exploded and shocked America.

I speak to best-selling author Adam Higginbotham about his minute-by-minute account of the tragedy.

Plus, hopes of progress in Gaza.

But in the West Bank, Israeli settler violence continues to decimate villages.

Jeremy Diamond reports.

Also ahead, Christian's conversation

with the Holocaust survivor and legal titan. Ninety-five-year-old Judge Theodore Moron reflects

on a lifetime pursuing justice.

I must admit that we live in a moment of retraction, a retrogressive step for international criminal justice.

And as the world marks Holocaust Remembrance Day this week from Christian's archive,

how the Nazi slaughter of six million Jews shocked the world into outlawing genocide once and

for all.

Welcome to the program, everyone.

I'm Biona Gola Drega, New York, sitting in for Christian.

As the United States faces chaos within and creates instability beyond its borders,

are America's oldest allies hedging their bets.
