During World War II, the United States teamed up with the Soviet Union to defeat Nazi Germany. It was an alliance built on a common interest, albeit one that involved a partner with whom we predictably came to be at odds. This hour, we’ll talk about the tricky business of working with other nations while maintaining our values with Ted Galen Carpenter, co-author of “Perilous Partners: The Benefits and Pitfalls of America’s Alliances with Authoritarian Regimes” (Cato Institute). Ted Galen Carpenter speaks Tuesday to the World Affairs Council of Dallas/Fort Worth.
