    In this timely and controversial examination of civilian-military relations in wartime democracies, Eliot A. Cohen chips away at this time-honored belief with case studies of statesmen who dared to prod, provoke, and even defy their military officers to great effect.Using the leadership of Abraham Lincoln, Georges Clemenceau, Winston Churchill, and David Ben-Gurion to build his argument, Cohen offers compelling proof that, as Clemenceau put it, “War is too important to leave to the generals.” By examining the shared leadership traits of four politicians who triumphed in extraordinarily varied military campaigns, Cohen argues that active statesmen make the best wartime leaders, pushing their military subordinates to succeed where they might have failed if left to their own devices. Thought provoking and soundly argued, Cohen's Supreme Command is essential reading not only for military and political players but also for informed citizens and anyone interested in leadership.

    Allen and Cowling start with the simple "prokaryotic" cell--cells with no nucleus--and show how the bodies of more complex plants and animals consist of billions of "eukaryotic" cells, of varying kinds, adapted to fill different roles--red blood cells, muscle cells, branched neurons. The authors also show that each cell is an astonishingly complex chemical factory, the activities of which we have only begun to unravel in the past fifty years.

    military found itself in a battle with a lethal and adaptive insurgency, where the divisions between enemy and ally were ambiguous at best, and working with the local population was essential for day-to-day survival. From the lessons they learned during multiple tours of duty in Iraq, two American veterans have penned The Defense of Jisr al-Doreaa, an instructional parable of counterinsurgency that addresses the myriad of difficulties associated with war in the postmodern era. In this tactical primer based on the military classic The Defence of Duffer’s Drift, a young officer deployed for the first time in Iraq receives ground-level lessons about urban combat, communications technology, and high-powered weaponry in an environment where policy meets reality. Over the course of six dreams, the inexperienced soldier fights the same battle again and again, learning each time—the hard way—which false assumptions and misconceptions he needs to discard in order to help his men avoid being killed or captured. As the protagonist struggles with his missions and grapples with the consequences of his mistakes, he develops a keen understanding of counterinsurgency fundamentals and the potential pitfalls of working with the native population. Accompanied here by the original novella that inspired it, The Defense of Jisr al-Doreaa offers an invaluable resource for cadets and junior military leaders seeking to master counterinsurgency warfare—as well as general readers seeking a deeper understanding of the wars in Iraq and Afghanistan. Just as its predecessor has been a hallmark of military instruction, The Defense of Jisr al-Doreaa will draw the road map for counterinsurgency in the postmodern world.   Visit a website for the book here: www.defenseofJAD.com
