Zoom in: Organizers set "rebuilding trust" among leaders as the theme of this year's annual meeting of the World Economic Forum. It's a worthy one given the threat of geopolitics on business. However, AI took center stage.
Why it matters: The last time the two leaders spoke was on Dec. 23, when a frustrated Biden ended the call by saying the "conversation is over" and hanging up the phone. In the first two months of the war, the two leaders had talked almost every other day.
While the U.S. has been focused on Gaza and Ukraine, several other long-simmering global threats are getting hotter.
Why it matters: The last 72 hours have seen menacing Chinese patrols near Taiwan, an exchange of fire between Iran and Pakistan, and further escalation between the U.S. military and Houthi rebels.
NATO is mobilizing some 90,000 troops for its biggest military exercise since the Cold War.
The big picture: "That is a record number of troops that we can bring to bear and have an exercise within that size, across the alliance, across the ocean, from the U.S. to Europe," said NATO Military Committee chair Adm. Rob Bauer at a briefing announcing the plans Thursday.
