I think that NixonNow means that prior to the Oklahoma City bombing, McVeigh was a decorated veteran having served in the Gulf War, where he earned a Bronze Star. See
Wikipedia Entry. Not that Cleland and McVeigh are comparable, the argument is a polarized example that a "war hero" does not necessarily translate into qualifications for other jobs. NixonNow - the argument is stronger if additional data is used in conjunction with your statement. Timothy McVeigh is not known for his war hero history, and therefore the one-liner could easily be mis-interpreted that this bombing in Oklahoma City was heroic to some fringe group.
