Bush and Blair had a secret plan to win the Iraq war -- and they won the war!
There wasn't anything secret about their plan to invade Iraq.
You switch context of the word plan to suit your need.
Everybody knew that Nixon had a plan to win the Vietnam War. It was the specifics of the plan that was secret. Likewise everybody knew that Blair and Bush planned to invade Iraq. It was the specifics of the plan that was secret.
Why don't you quit play cute word games and come right out and say that you don't believe Blair and Bush have secret information abount WMD finds in Iraqi?
