One can wonder whether another book on the U.S.-Israeli relationship is really needed, but this one at least has the virtue of being well-written and filled with tidbits of inside information. No grand theoretical framework is offered to explain this intimate connection. The authors, who have written about intelligence matters before, tend to see the strategic sinews of the relationship as particularly important, which was especially true during the 1980s, but may be a waning asset. One can also question the view that "the United States usually can impose its will on Israel without twisting any arms." The authors recognize that the relationship will inevitably change as time passes, but they remain sanguine that the two sides are tightly linked by interests and sentiment.
