I'd have to say "No" to that. I wouldn't make a good leader for my country because I'd tend to champion 'world causes' rather than 'national causes.'
I was disappointed when, years ago, JFK gave his inaugural address. "Ask not what your country can do for you: ask what you can do for your country."
Had he said, "Ask not what the world can do for you: ask what you can do for the world."
Had he said that, he would truly have been regarded as a world leader, a real world-class statesman. Instead, he chose to be just one more national leader.
