When Acheson reported this shocking incident [March 22nd] to Truman, the president was dismayed. He probably made the decision that day that Johnson must be replaced; but his debt to Johnson was large, and he did not pursue the search for a new defense secretary with any vigor. However, he privately laced into Johnson, with the result that when NSC68 reached Johnson's desk on April 6, signed by Acheson, the JCS, and other senior strategists, Johnson put his signature on it without pause. As Acheson aptly commented, "Johnson was not left in a strong offensive position."[1-42]
