When we talk about prevention in health care we are talking about doing something about the root course.

In terms of terrorism that's having a foreign policy that doesn't make citizens of other countries want to bomb your country and having internal politics that no secession movement wants to bomb your country.

And both these facts are true. But... they contradict each other.

No. If you have to invest into strong security that's a sign that you didn't do anything to prevent the threat from arising in the first place.

One is about a lack of prevention, the other about an excess of prevention. And there are more examples of excessive prevention: the war on drugs

The war on drugs doesn't prevent anything. Decriminalization in Portugal didn't increase the amount of drug use. The war of drugs is about punishing people who take drugs or deal drugs, it's not about prevention at all.

There's not enough money spent to prevent the social conditions that lead to drug use.
