In a new op-ed in The Wall Street Journal, Mitt Romney argues that President Obama and former secretary of state Hillary Clinton have repeatedly missed opportunities to assert leadership and guide world events.

"Their failure has been painfully evident: It is hard to name even a single country that has more respect and admiration for America today than when President Obama took office, and now Russia is in Ukraine," Romney writes. "Part of their failure, I submit, is due to their failure to act when action was possible, and needed."

Romney argues that there were moments early in the conflicts in Egypt and Syria when the United States could have played a role to avert much more difficult circumstances down the road.

He also suggests that Obama and Clinton haven't done a good job of foreseeing possible future invents, instead dealing with crises after they happen.

"Able leaders anticipate events, prepare for them, and act in time to shape them," Romney writes. "My career in business and politics has exposed me to scores of people in leadership positions, only a few of whom actually have these qualities. Some simply cannot envision the future and are thus unpleasantly surprised when it arrives. Some simply hope for the best. Others succumb to analysis paralysis, weighing trends and forecasts and choices beyond the time of opportunity."
