Not trying to be confrontational or pedantic (there’s enough bickering in here) but it’s important to state that the Korean War is quite literally called “The Forgotten War”. In fact, it’s more important to point out that it wasn’t even a War, but considered a “police action” that claimed the lives of up to 3 million civilians (link).

Council on Foreign Affairs

Truman acted without seeking congressional authorization either in advance or in retrospect. He instead justified his decision on his authority as commander in chief. The move dramatically expanded presidential power at the expense of Congress, which eagerly cooperated in the sacrifice of its constitutional prerogatives.

Robert A. Taft of Ohio, one of the leading Republicans on Capitol Hill at the time, took to the Senate floor on June 28 to argue that “there is no legal authority for what he [Truman] has done.” Nor could Truman argue that the Korean conflict didn’t constitute war in a constitutional sense, even if he did downplay the significance of his decision. (At a press conference on June 29, Truman denied the country was at war, prompting a journalist to ask, “would it be correct…to call this a police action?” Truman answered simply, “Yes.”

Truman in the end acted because he believed, contrary to what the framers envisioned and the historical record showed, that as commander-in-chief he had the authority to order U.S. troops into combat… Truman was able to establish the precedent that presidents can take the country to war, though, because members of Congress were unwilling, Taft’s complaints notwithstanding, to defend their constitutional power from executive encroachment.

You can’t look at those statements and not make parallels to what’s going on in America today with the executive branch trying to sequester even more power. Ironically just recently saw a pretty decent video on the war by Mr. Beat
