On GPS Sunday: A closer look at the inequality debate, and Kissinger on Ukraine

Watch "Fareed Zakaria GPS," Sundays at 10 a.m. and 1 p.m. ET on CNN

On GPS this Sunday: In the wake of President Obama's State of the Union address, Fareed convenes a panel looking at the issue of inequality in the United States. Zanny Minton Beddoes, economics editor of The Economist, Steve Rattner, the Obama administration’s “car czar,” Canadian member of parliament Chrystia Freeland and former IMF Chief Economist Ken Rogoff offer their takes on this and more.

Then, our “What in the World?” segment looks at the economic costs of smoking – and whether obesity could be next in line for intervention by policymakers.

Later, a look at the ongoing political crisis in Ukraine – and why Kiev can't shake off Moscow’s influence. Former Secretary of State Henry Kissinger explains the nature of Russia’s role.

Also, an insider's perspective on Russian President Vladimir Putin, from a close friend: the famous conductor Valery Gergiev.
