As NATO turns 70 this year, questions abound about its strength in the face of Russian resurgence and U.S. isolationism. Born in 1949, NATO emerged as a political alliance of 12 North American and European countries. It quickly became a military alliance, ultimately growing to 29 members. More recently, President Trump has threatened to withdraw the U.S. from NATO, arguing that the alliance’s other members are taking advantage of the U.S. and its resources. So what does NATO’s future look like amid shifting security threats and political strategies? Joining Worldview to discuss are several former U.S. ambassadors to NATO. Victoria Nuland was the U.S. Ambassador to NATO from 2005-2008. Ivo Daalder had the same role from 2009-2013 and Douglas Lute served from 2013-2017. Daalder is also the president of the Chicago Council on Global Affairs, which hosted a discussion about NATO’s past and future on Tuesday night.
