The United States became physically involved in Vietnam in the late forties in the capacity of military advisers. The US was initially allied with the French, and when the French departed in 1954, the United States became the primary military foreign government presence in the country. The United States military was slowly drawn, (by in country conflict) and tugged (by Viet Cong Allies namely the Soviet Union) into the armed conflict. Albeit, a civil war and the US government should not have been involved
in the sovereign conflict which persisted between the internal factions, these were very uncertain times during the Cold War with Russia, and it was viewed as ill advisable to
permit the Russians to have unfettered access. That being said, the United States did not have a short or long range war plan for Viet Nam. No one in the Department of Defense, or the White House, had any idea of how much it was going to cost, or how long it was going to take. In this regard, when the US military was deployed into harms way in Iraq, the circumstances were similar to the debacle of Vietnam; yet different. Americans and American soil had been violated by individuals who were domiciled in Iraq There was a need to seek out and avenge these acts. However, The President himself thought it was over before it was over. Which only goes to show that they did not adhere to the six P’s (Proper Planning Precludes a Pitifully Poor Performance) after what they characterized as the fall of Baghdad.
