We see vary opposite sides of the same coin my friend. My Marine experience is that they don’t “respect” the effect of the short term horizon of presidential politics on the death of their men. They’re “faithfully” and rightfully consumed with avoiding a repetition of the lunacy of Vietnamization
And in the case of Fallujah, they’ll go so far as to prematurely insert a skeletal Fallujah “brigade” rather that sacrifice more of their men to a CIC gone wobbly. God Bless those guys!
Vietnamization failed when it didn't include the whole fight from invasion/bombing of all enemy areas and mining Haiphong. Iraq will fail too if we don't stop Syria and Iran.
Since Viet Nam, the Marines have learned to fight smarter, they will solve the Falluja riddle.
