Exactly, so you're really talking out of your butt on things you know absolutely nothing about, once again. I really don't care what you heard from Walter Cronkite, you were not there, you do not have access to internal documents, and you do not know what it was like.I am not a war hawk, but I am also not a conspiracy theorist like you. The leaders of our nation are not intentionally leading us all to ruin; they really do have the nation's best interests at heart even though I may vehemently oppose their tactics or actions of accomplishing their goals. Vietnam was a new kind of war. The U.S. was not used to fighting a war like that; in many ways they still aren't fully up to the task. THAT SAID, the government is very much like a surgeon or doctor...even if the patient is likely not going to do well, they have an obligation to play up the positives because surgery, like war, is at least 50% mental. If you think you're going to win, you're more likely to triumph because the patients/public are more enthusiastic about the surgery/war and are more likely to give it their all when they are fighting the cancer/war.
Were we in Vietnam too long? Oh, most definitely, but the issue is not so black and white. There were many politically-charged issues with pulling out of the war: Americans had never really lost a war, except for the half of the nation that lost the Civil War. Also, pulling out would be a sign of weakness to our allies and other nations around the world. We were in the midst of a Cold War with Russia and had very little idea what was going on in their side of the Iron Curtain. We now know America was soundly advanced of the Soviets, but this was NOT known at the time, and it really was best to take a conservative approach that the Soviets could and would expand Communism in politically turmoiled nations, which at that time was a direct threat to American interests and the beginning of America's globalization.
Of course, I don't really expect you to understand the complex nature of the politics surrounding the Vietnam War because you have repeatedly demonstrated a severe lack of knowledge of the complexities involving the automotive industry, which in turn is infinitely less complicated than international politics during warfare.
