Since President Barack Obama took office in 2009 — from Afghanistan to Iraq, from Greece to Ukraine — wars, crises, and upheaval have rewritten the geopolitical pecking order. In this special edition of The E.R. podcast, our panel asks who has been the biggest winner of them all, the most successful leader in the world since 2008. Hint: Angela Merkel scored well, but still finished fourth.
Robert Kagan is a historian, best-selling author, and columnist at the Washington Post. He is also a senior fellow at the Brookings Institution.
