Very interesting, factual, and not racial, SMT, not least because "the enemy within "as you describe it, is presumably highly motivated by the fact that "we are away fighting campaigns on two fronts".
Whilst 1.4g's last sentence is perfectly correct, his first sentence shows that he has completely missed the point - to rephrase the sign hung in Bill Clinton's campaign headquarters, "It's the enemy within, stupid!"
