in the administration of President Harry S. Truman
from 1949 to 1953, he played a central role in defining American foreign policy during the Cold War
. Acheson helped design the Marshall Plan
and played a central role in the development of the Truman Doctrine
and creation of the North Atlantic Treaty Organization.
Acheson's most famous decision was convincing President Truman to intervene in the Korean War
in June 1950.
I am willing to join in your statement on the ground that I feel about the future of the United States whenever the President starts out on his travels the way the Marshal of the Supreme Court does when he opens a session of that Court. You will recall that he ends up his liturgy by saying "God save the United States for the Court is now sitting."
Vietnam was worse than immoral — it was a mistake.
"The experiences of the years...have brought the country, particularly its young people, to a mood of depression, disillusion, and withdrawal from the effort to affect the world."
In response, Acheson wrote to "tell a tale of large conceptions, great achievements...Its hero is the American people."
"Plainly plenty of work was waiting to be done. The question was: would the State Department do it? I proposed to have a shot at finding out."
General Marshall was "impatient with a type of nonsense particularly prevalent in the State Department known as 'kicking the problem around.' All of us who have work with General Marshall have reported a recurring outburst of his: 'Don't fight the problem, gentlemen, solve it!' With him the time to be devoted to analysis of a problem, to balancing 'on the one hand' against 'on the other hand,' was definitely limited. The discussion he wanted was about plans of action "
"I must plead guilty as any of escaping into immediate busywork to keep the far harder task of peering into a dim future, which, of course, should be one of a diplomat's main duties."
"My memory...is of a department without direction, composed of a lot of busy people working hard and usefully but as a whole not functioning as a foreign office. It did not chart a course to be furthered by the success of our arms, or to aid or guide our arms. Rather it seems to have been adrift carried hither and yon by the currents of war or pushed about by collisions with more purposeful craft."
"Among the roles the Budget Bureau (now OMB) was that of constant critic and improver of administration in the federal executive branch. In my day this work had fallen to the products of graduate schools in civil administration. Their ideas...seemed to me theoretical nonsense."
