That can be said for every country. Not every country is a target of a terrorist attack though.

I look both ways when I cross the street.

If you don't look, there is a higher probability of being hit by a car. Therefore, you're trying to control the probability of being hit by a car. You can't do that in regards to a terrorist attack.

I don't check my car for bombs every morning.

Of course not. A bomb on your car would be an attack directly towards you, and you know there is a low probability of that happening.

You weren't directly affected by 9/11, but many people were (or by the London and Madrid bombings, for instance). Of course people are also affected when someone close to them dies prematurely, but as pyre already replied to you, people accept those random causes better than they do accept a terrorist attack.
