You're right about that, but it's worth noting that many of those "other" reasons on that long list are even worse than that one.
"No it was only one of, on a long list or reasons to go to war . . ."
"even worse reasons"
If you think that, OK, but I think they are ALL good reasons.
Not the least of which is Al Qaida declared War on us, and Pres Clinton ignored it, at our loss!
