You must have missed that whole Iraq invasion, subsequent capture, conviction, and execution of Saddam Hussein.
John Doe #2 was an Iraqi Agent. The target detonation date was set by Iraq for the day of the Branch Davidian church burning by the BATF in order to stoke local Texas anti-government feelings. The Iraqi plan was for McVieigh to bomb something in Bush's city of Dallas (back when he owned the Texas Rangers) or in Austin (when he was Governor of Texas) in retaliation for GHWB's 1991 invasion of Iraq...but McVeigh didn't want to drive that far South.
OKC was closer. In the end, detonating the bomb in OKC was a complete failure. No "message" was sent to Bush in Texas and no Texas uprising against the government occurred...because bombing OKC didn't have the same emotional impact that bombing in Texas would have.
Had the plot been made public, however, there would have been immediate calls for an Iraq invasion...something that Clinton didn't want.
...but when Bush took over as President, the various Iraqi plots (one against his dad in Kuwait comes to mind) weighed in to subsequent action against Hussein.
So something was done. Saddam was executed for the OKC plot, among other things.
NO! I only missed the connection between the invasion and J.Doe#2???
I feel like a mushroom.(if you don't, know look it up)
