Would-be asteroid collision diverters, space solar energy collectors, asteroid miners, and space geo-engineers insistently promote their Earth-changing mega-projects. Given our many looming planetary catastrophes (from extreme climate change to runaway artificial superintelligence), looking beyond the earth for solutions might seem like a sound strategy for humanity. And indeed, bolstered by a global network of fervent space advocates—and seemingly rendered plausible, even inevitable, by o...

By the last decade of the twentieth century, the great questions of modernity seemed to be answered. With the collapse of the Soviet Union and global communism, the liberal democratic capitalist project seemed to be the only one left standing, and in the 1990s the "liberal ideal" spread worldwide. Today, of course, this universalistic narrative rings hollow. The global distribution of power has shifted and the preeminence of the West is receding as new directions for world order emerge. Ch...

Space is again in the headlines. E-billionaires Jeff Bezos and Elon Musk are planning to colonize Mars. President Trump wanted a "Space Force" to achieve "space dominance" with expensive high-tech weapons. The space and nuclear arms control regimes are threadbare and disintegrating. Would-be asteroid collision diverters, space solar energy collectors, asteroid miners, and space geo-engineers insistently promote their Earth-changing mega-projects. Given our many looming planetary catastroph...

Realism, the dominant theory of international relations, particularly regarding security, seems compelling in part because of its claim to embody so much of Western political thought from the ancient Greeks to the present. Its main challenger, liberalism, looks to Kant and nineteenth-century economists. Despite their many insights, neither realism nor liberalism gives us adequate tools to grapple with security globalization, the liberal ascent, and the American role in their development. I...

A great deal of the world's history is the history of empires. Indeed it could be said that all history is colonial history, if one takes a broad enough definition and goes far enough back. And although the great historic imperial systems, the land-based Russian one as well as the seaborne empires of western European powers, have collapsed during the past half century, their legacies shape almost every aspect of life on a global scale. Meanwhile there is fierce argument, and much speculati...

If the European Union applied to become a member of the European Union it would be rejected as undemocratic. Can the European Union foster greater democracy in Europe, and so protect the dispersal of power, personal freedom and the rule of law? Willit improve our shared lives and increase sense of being useful citizens? Rejecting both nostalgia for the nation state and thoughtless optimism, Larry Siedentop sets out to explore the practical implications of government on a continental scale....

Geopolitics is a way of looking at the world: one that considers the links between political power, geography, and cultural diversity. In certain places such as Iraq or Lebanon, moving a few feet either side of a territorial boundary can be a matter of life or death, dramatically highlighting the connections between place and politics. Even far away from these 'danger zones' - in Europe or the US for example - geopolitics remains an important part of everyday life. For a country's location an...

"A fascinating historiographical essay. . . . An unusually lucid and inclusive explication of what it ultimately at stake in the culture wars over the nature, goals, and efficacy of history as a discipline."—Booklist

We are living through a period of dramatic political change – Brexit, the election of Trump, the rise of extreme right movements in Europe and elsewhere, the resurgence of nationalism and xenophobia and a concerted assault on the liberal values and ideals associated with cosmopolitanism and globalization. Suddenly we find ourselves in a world that few would have imagined possible just a few years ago, a world that seems to many to be a move backwards. How can we make sense of these dramati...
