"...as a candidate courting his party’s conservative base, Romney has issued foreign-policy pronouncements with a harder line. He says his administration would align closely with Israel, view Russia as the United States’ primary geostrategic foe and label China as a currency manipulator. The population of terrorist suspects at the Guantánamo Bay military prison might double, and “enhanced interrogation techniques” such as waterboarding could return to the counterterrorism toolbox. A Romney administration purportedly would increase defense spending and bolster rather than shrink the size of the U.S. military. There would be no diplomacy with Iran, which would be enjoined to abandon its nuclear-weapons ambitions or else. U.S. military forces would remain in Afghanistan until the Taliban is defeated decisively." Kifield
