Dan Drezner takes to the pages of Foreign Affairs to explain how the GOP squandered a decades-old advantage with the voters on foreign policy.

So how did the party of Dwight Eisenhower and Ronald Reagan get itself into this mess? Simply put, GOP leaders stopped being smart foxes and devolved into stupid hedgehogs. During the Cold War, the party of Eisenhower, Richard Nixon, and Reagan was strongly anticommunist, but these presidents took foreign policy seriously and executed their grand strategies with a healthy degree of tactical flexibility. Since 9/11, however, Republicans have known only one big thing -- the "global war on terror" -- and have remained stubbornly committed to a narrow militarized approach. Since the fall of Baghdad, moreover, this approach has produced at least as much failure as success, leading the American public to be increasingly skeptical of the bellicosity that now defines the party's foreign policy.

Since 9/11, Republicans have known only one big thing -- the "global war on terror" -- and have remained stubbornly committed to a narrow militarized approach. Republicans need to start taking international relations more seriously, addressing the true complexities and requirements of the issues rather than allowing the subject to be a plaything for right-wing interest groups. And if they don't act quickly, they might cede this ground to the Democrats for the next generation.
