The current dilemma in Vietnam is a clear demonstration of the limitations of military power ... [Current U.S. involvement] is a policy of moral debacle and political defeat ... The trap we have fallen into there will haunt us in every corner of this revolutionary world if we do not properly appraise its lessons.On the invasion of Iraq:
Every Senator in this chamber is partly responsible for sending 50,000 young Americans to an early grave. This chamber reeks of blood. Every Senator here is partly responsible for that human wreckage at Walter Reed and Bethesda Naval and all across our land—young men without legs, or arms, or genitals, or faces or hopes. There are not very many of these blasted and broken boys who think this war is a glorious adventure. Do not talk to them about bugging out, or national honor or courage. It does not take any courage at all for a congressman, or a senator, or a president to wrap himself in the flag and say we are staying in Vietnam, because it is not our blood that is being shed. But we are responsible for those young men and their lives and their hopes. And if we do not end this damnable war those young men will some day curse us for our pitiful willingness to let the Executive carry the burden that the Constitution places on us.
I oppose the Iraq war, just as I opposed the Vietnam War, because these two conflicts have weakened the U.S. and diminished our standing in the world and our national security.In an open letter to Barack Obama, 2008:
When I entered the U.S. Senate in 1963, the defense budget was $51 billion. This was at a time when our military experts felt it necessary to have the means to win a war against the combined powers of Russia and China. Today we have a military budget of over $700 billion, and yet neither Russia nor China threatens us, if indeed they ever did. Nor does any other nation.
