In 1945 the United States saw the Soviet Union as its principal ally. By 1947, it saw the Soviet Union as its principal opponent. How did this happen? Historian John Lukacs has provided an answer to this question through an exchange of letters with George F. Kennan. Their correspondence deals with the antecedents of containment between 1944 and 1946, during most of which time Kennan was at the American embassy in Moscow.

Kennan had strong opinions about America's appropriate role during and after World War II and is perhaps best known as the architect of America's containment policy. Much has been written about Kennan and containment, but relatively little is known about the events that made him compose and send the Long Telegram in 1946 that ultimately became the draft for foreign policy dealing with the Soviets in the following forty years.

These letters show Kennan's fear of the extent to which the United States misunderstood the Soviet regime. Especially in 1944, at the time of the Russians' betrayal of the Warsaw Uprising, it became evident that the Soviets were interested in establishing their rigid domination of Eastern and Central Europe and dividing the continent.

Kennan's letters to Lukacs are thorough and detailed, suggesting that the Truman administration was not in the least premature in opposing the Soviet Union. Indeed, both correspondents suggest that these decisions should have been made earlier. This series of letters will add greatly to our understanding of what preceded containment and the Cold War in 1947.

Fresh water has become scarce and will become even more so in the coming years, as continued population growth places ever greater demands on the supply of fresh water. At the same time, options for increasing that supply look to be ever more limited. No longer can we rely on technological solutions to meet growing demand. What we need is better management of the available water supply to ensure it goes further toward meeting basic human needs. But better management requires that we both understand the history underlying our current water regulation regime and think seriously about what changes to the law could be beneficial.

For Golden Rules, Mark Kanazawa draws on previously untapped historical sources to trace the emergence of the current framework for resolving water-rights issues to California in the 1850s, when Gold Rush miners flooded the newly formed state. The need to circumscribe water use on private property in support of broader societal objectives brought to light a number of fundamental issues about how water rights ought to be defined and enforced through a system of laws. Many of these issues reverberate in today’s contentious debates about the relative merits of government and market regulation. By understanding how these laws developed across California’s mining camps and common-law courts, we can also gain a better sense of the challenges associated with adopting new property-rights regimes in the twenty-first century.
