Rubio and the Return of the Monroe Doctrine

President-elect Donald Trump on Wednesday tapped Florida senator Marco Rubio (R.) to lead the State Department. Rubio is, among other things, a full-spectrum opponent of China's nefarious activities, and the news of his nomination dismayed the soft-on-China crowd. He is also tough on Iran and should focus America's diplomats on promoting the nation's interests rather than exporting the culture wars. But Rubio's most distinctive foreign policy contribution is likely to be in Latin America, where he can bring the Monroe Doctrine back to the center of U.S. foreign policy.
