This is GPS, the Global Public Square.

Welcome to all of you in the United States and around the world.

I'm Farid Zakaria, coming to you from Davos, Switzerland.

Today on the program, I talk with the leaders of four of Russia's neighbors to the West,

starting with Ukraine's president, Silents.

I ask under what conditions he would be willing to negotiate with Vladimir Putin.

Then President Duda Poland explains just how much suffering Russia has caused his nation in the past.

And top ministers from Finland and Sweden tell me about their nation's historic decisions to apply for NATO membership.

Then a rare interview with Iran's foreign minister at a critical time in talks for a revived nuclear deal.

We make sure that an Iran that is already acting with incredible aggression doesn't have a nuclear weapon or the ability to produce one on short notice.

Will they reach an agreement or will the talks fall apart?

When in God's name, we do, we all know our gut needs to be done.

Finally, one more senseless act of violence this time in Texas.

I'll give you some of my thoughts on how to end this endless carnage.

But first, here's my take.

The World Economic Forum in Davos is usually fixated on the future.

Most years, the attendees are dazzled by some country, company or technology promising to burst forward, force change, dominate the next decade.

This year, the focus was not on the future, but the past.

People delved back into history to debate what caused Russia's invasion of Ukraine.

The Swedish Finance Minister explained why his country, which hasn't been at war since the Napoleonic Wars, was breaking its 200-year tradition of neutrality with his bid to join NATO.

The Finnish Foreign Minister recalled Finland's resistance to Moscow's aggression in the Winter War of 1939 and 1940.

In past years, at Davos, companies took storefronts and plastered them with jubilant signs cheering on dynamism, acceleration and disruption.
