Excerpt: So why do America’s disastrous wars persist? I can think of many reasons, some obvious and easy to understand, like the endless pursuit of profit through weapons sales for those very wars, and some more subtle but no less significant, like a deep-seated conviction in Washington that a willingness to wage war is a sign of national toughness and seriousness. Before I go on, though, here’s another distinctive aspect of our forever-war moment: Have you noticed that peace is no longer even a topic in America today? The very word, once at least part of the rhetoric of Washington politicians, has essentially dropped out of use entirely. Consider the current crop of Democratic candidates for president. One, Congresswoman Tulsi Gabbard, wants to end regime-change wars, but is otherwise a self-professed hawk on the subject of the war on terror. Another, Senator Bernie Sanders, vows to end “endless wars” but is careful to express strong support for Israel and the ultra-expensive F-35 fighter jet. The other dozen or so tend to make vague sounds about cutting defense spending or gradually withdrawing U.S. troops from various wars, but none of them even consider openly speaking of peace. And the Republicans? While President Trump may talk of ending wars, since his inauguration he’s sent more troops to Afghanistan and into the Middle East, while greatly expanding drone and other air strikes, something about which he openly boasts.
