Mitt Romney says President Barack Obama could have done more to persuade Russia not to annex Crimea.
Romney says Obama didn't have the foresight to anticipate Russia's intentions.
During the 2012 presidential race, Romney took criticism from Obama for saying Russia was America's "number one geopolitical foe" — not al-Qaida.
Now Romney is using Russia's action in Crimea as a way to sort of say "I told you so."
Romney tells CBS's "Face the Nation" that Obama's "naivete" and "faulty judgment" about Russia has led to a number of foreign policy challenges.
Romney says the U.S. should have worked sooner with allies to make clear the penalties that Russia could have faced if it moved into Ukraine.
Romney acknowledges that would only have had the potential for preventing the invasion.
