Didn't the Democratic [North] Vietnamese slaughter thousands upon thousands of Vietnamese Christians, a practice that they continue unto this very day?
The following books by Dooley, Edge of Tomorrow, The Night They Burned the Mountain and Deliver Us from Evil were major propaganda tools in inflaming the American populace toward action, especially Catholics. Communist attacks on Vietnamese Catholics are documented in these books.
Dooley was a complicated person and there is reason to doubt some of the claims in these books but their role in the late 1950s and past his death in 1961 in preparing Americans for war can not be denied.
