Lincoln established the unconstitutional precedent of a president waging war without congressional approval. The following is drawn from a chapter entitled “A Costly Mistake: War Without Congressional Approval.” As a note of clarification, Sen. Robert Taft was not an “isolationist” but an anti-interventionist who advocated avoidance of European or Asian wars, concentrating instead on solving its domestic problems. He advocated a strong American military as adequate protection and opposed Truman’s unconstitutional actions.
Truman’s War Bypasses Congress
“After Sen. Scott Lucas of Illinois had read to the Senate on June 27 Truman’s initial statement committing US air and naval forces and ordering the fleet to neutralize Formosa, Senator James P. Kem, Republican of Missouri, rose: “I notice that in the President’s statement he says ‘I have ordered the fleet to prevent any attack on Formosa.’ Does that mean he has arrogated to himself the authority of declaring war?”
“A state of emergency exists,” Lucas said, ignoring the fact that Truman had not legally declared one. Based on the action of the United Nations Security Council,” Lucas explained, the President of the United States has ordered action. It is a demonstration of our keeping the faith.”
Republican Senator John Bricker of Ohio interposed, “Am I correct in saying that the President’s action was taken as a result of the cease-fire order issued by the Security Council? Lucas said that Bricker was correct as far as action in Korea was concerned. Watkins declared that Truman had taken a step leading toward war.
“The Congress is now in session,” the senator said, “and unless there is power in the United Nations to order our forces into action of this kind which may result in a major world clash, then I think we should have been informed by the President in a message to Congress today. As I recall, we were told time and time again when we were considering the [North Atlantic Treaty Organization] that nothing would take us into war under that pact without action by Congress. The President could not do it . . . Now, according to the action taken, by the mere order and request of the United Nations, our troops can be sent into a fighting war without Congress saying ‘yes or no.’
Article I, Section 8 of the Constitution provides that Congress shall have the power to declare war.
The big gun went off in the Senate on June 28. In a crackling speech, Robert Taft, “an old-time isolationist” to Truman – alleged:
“a complete usurpation by the President of authority to use the armed forces of the country. His action has brought about a de facto war with the government of northern Korea. He has brought that war about without consulting Congress and without congressional approval. We have a situation in which in a far-distant part of the world one nation has attacked another, and if the President can intervene in Korea without congressional approval, he can go to war in Malaya or Indonesia or Iran or South America.” With but the slightest detour on a map Taft might have included Vietnam.
“Mr. President”, a reporter asked, “everybody is asking in this country, are we or are we not at war?”
“We are not at war,” Truman replied and later added that “the members of the United Nations are going to the relief of the Korean Republic to suppress a bandit raid . . .”
“Mr. President, would it be correct, against your explanation, to call this a police action under the United Nations?”
Truman responded, “Yes, that’s exactly what it amounts to . . .”
Again, Truman had let a reporter put words in his mouth that were later to be held against him. He did not initiate, nor volunteer, the phrase “police action” any more than he had “red herring,” but the result was to be the same as if he had.”
