Fight the war that's there and win it, not Vietnam all over again and lose.
It just makes sense. Frankly, 7 years on top of Vietnam is a long, long time and long enough to learn the lesson.
The stupidity of continuing to do what has failed for 7 long, hard, expensive years, as you suggest doing, is simply amazing. You want to lose this situation. There is no other explanation.
And your goal is to keep the military-industrial folks going. Because, except for the situation worsening, that's all that's going on.
Well, and some families missing sons, daughters, mothers, fathers and so on. But you give them medals.
