Are you fucking kidding? Google Gulf of tonkin if you are so unbelievably uninformed about how VietNam escalated.
1) I am not saying it was not a lie.
2) Who told that lie? Where is the quote? (I can give you several Bush quotes that were absolute lies in his direct charge to war)
3) Our involvement in Vietnam was an incremental thing that was pushed some by the gulf of Tonkin, but was not the direct result.
4) Blame for Vietnam is spread over a broad base of people and over a long period of time, mostly the Johnson Administration but clearly not as directly as Iraq can be blamed on Bush.
5) Waaahhh, they did it to, back in 1970, does not make what Bush did any better.
