I also hope that we find these WMDs, if they still exist to be found. However, it may very well be the case that these WMDs were destroyed or hidden just before the war began (or, for that matter, during the war as well). We certainly need to get to the bottom of what happened to these weapons (a process that may take months) so that to the extent they still exist we can account for them, track them down, secure them, and thereby keep them out of the hands of the wrong people.
But it would have been so easy to give them to the wrong people just out of spite? Is that wrong to assume? Are we safer?
