Query: Old wine in a new bottle

Using new evidence from the Abrams papers, but failing to examine massive recent declassifications of Nixon's and others' papers and tapes, including Soviet, Chinese, and Vietnamese documents and accounts, Sorley essentially restates the mythical stab-in-the-back theory; namely, that the antiwar movement and the politicians betrayed a victorious army. Readers need to read Kimball's Nixon's Vietnam War and The Vietnam War Files; David Elliott's The Vietnamese War; Kenton Clymer's The United States and Cambodia; Luu Van Loi and Nguyen Anh Vu's Le Duc Tho-Kissinger Negotiations; and Ang Chen Guan's Ending the Vietnam War.
