Go get the whole Courant Institute, this is barely more than the definition of probability.
Here is the way you originally stated your premise:
Quote:If WMD were no longer in Iraq by the time we invaded, then the next time we have the same situation, or the next, the WMD will still be there. That's what it means to talk about a probability.
That is an absurd contention...and a misapplication of probability theory and of logic.
If I can get someone more adept at explaining your error...I will, but from your comment above, if several statistic/probability experts were to show you that you were wrong...you would insist that you are correct anyway.
In any case, here are a few appropriate comments stated without attribution (simply because I do not know who wrote them.)
Our first intuitive ideas about probability can be fraught with fallacies, in that they sometimes do not obey the axioms they should
The appeal to probability is a (A fallacy in logical argumentation), often used in conjunction with other fallacies.
It assumes that because something could happen, it is inevitable that it will happen, irrespective of how unlikely it is. The fallacy is often used to exploit paranoia.
Some examples are:
There are many hackers that use the internet. Therefore, if you use the internet without a firewall, it is inevitable that you will be hacked sooner or later
AMD has been catching up to Intel in recent years. In a few years they will definitely take over Intel's position, and eventually put them out of business altogether.
When soccer becomes popular in a town, hooliganism will become a major problem. Thus, if we allow a soccer team in our town, we will be overrun by hooligans.
While not considered a "true" fallacy by some (owing to the fact that it is rarely used by itself), the appeal to probability is a common trend in many arguments, enough for many to consider it a fallacy of itself.
