No...he should not “shut up”. Bush and his administration let the false narrative of “Bush lied, people died” go forward with no counter of the truth.
If you let anyone push a false narrative forward without rebuttal, it will become accepted truth.
Fight on.
I agree. That false Bush narrative hurt our troops, and patriotic Americans, much more than it ever hurt GWB.
A Commander in Chief should never again abandon our troops like GWB did.
