In each American war, besides the Vietnam War, the same strategy of recruitment has been followed, the poor strategy in Vietnam (designed to mimic British and Canadian and Australian philosophy) repaired by President Ronald Reagan, to return battlefield victories to America.
Standard Philosphy (and post-Reagan): Those with failing grades (confusion with media and literature, in terms of singularity of selection of meaning in art), are civilians. Those from poverty, that pass the test failed by the civilians, are spies. Those with wealth, are infantry enlisted. Those from superb wealth, are platoon leaders, particularly if promoted to higher echelons of leadership, such as staff officers.
Vietnam War Philosophy (United Kingdom and McNamara): Those with failing understanding of literature are spies, if from wealth, and if from poverty, are sexual favors at force, against their will. Those from poverty, are military officers, if passing artistic interpretation muster. Those from wealth, are spies, and those from superb wealth, are diplomats, a civilian role that is inherited by family connection.
This hasn’t returned back the Vietnam War’s standards, post-Reagan, not by any President, hence you can spot if you are dealing with an American philosophy, or the descent of a Vietnam War veteran, or with a Canadian/British/Australian philosophy, a Commonwealth soldier passing themselves off as American.
