Memo from Executive Secretary, NSC, Subject: The Strategic Importance of Formosa, dated 4 March 1949

1.
Pursuant to NSC Action No. 189c and in accordance with your memorandum of 4 March 1949, the Joint Chiefs of Staff have considered the request for confirmation of the National Security Council’s interpretation of the Joint Chiefs of Staff’s estimate regarding the use of overt military action by the United States in Formosa.
2.
The National Security Council’s interpretation that this estimate means that overt military action by the United States in Formosa is not recommended by the Joint Chiefs of Staff, either at this time or under any foreseeable future circumstances, is generally correct, subject to the following considerations.
3.
The Joint Chiefs of Staff do not believe that the strategic importance of Formosa justifies overt military action at this time or in the event that diplomatic and economic steps prove insufficient to prevent Communist domination so long as the present disparity exists between our military strength and our global obligations. However, it should be pointed out that there can be no categorical assurance that other future circumstances extending to war itself might not make overt military action eventually advisable from the overall standpoint of our national security.
