If you're an angry driver, you'll flip someone the bird or ride their bumper or cause an accident. You can tell yourself that those other drivers are assholes, but it's just fear. If you're a multi-millionaire, you'll hire a lawyer to intimidate someone to give you what you want when you want it, so they won't do something that you can't control. You'll tell yourself it's just business, but it's really just fear. If you're a country with an anxiety problem, you'll attack another country. You'll tell yourself it's a matter of national security, but it's just fear. None of which ever solves the problem. All of which create bigger problems of their own.
When you're in a car and you see you're about to hit something, it's important not to overcompensate and swerve too far in the other direction, else you might run into something else. It's hard to think about this rationally, though, when overcome by the fear of an impending car accident. Fear is a useful motivator in emergency situations, but the rest of the time it tends to cause problems. We can see recent evidence of this in Iraq and America. When we spend so much energy worrying about what might happen, we can easily lose sight of what is happening.
