Afghanistan: Robert Gates: The Iraq War Undermined U.S. Efforts in Afghanistan --- The former secretary of defense also says that American foreign policy is too militarized and that politicians can't be trusted to do what's right. -- President Bush always detested the notion, but our later challenges in Afghanistan—especially the return of the Taliban in force by the time I reported for duty—were, I believe, significantly compounded by the invasion of Iraq. Resources and senior-level attention were diverted from Afghanistan. U.S. goals in Afghanistan—a properly sized, competent Afghan national army and police, a working democracy with at least a minimally effective and less corrupt central government—were embarrassingly ambitious and historically naive compared with the meager human and financial resources committed to the task, at least before 2009. -- With Obama ... I joined a new, inexperienced president determined to change course—and equally determined from day one to win re-election. Domestic political considerations would therefore be a factor, though I believe never a decisive one, in virtually every major national security problem we tackled. The White House staff—including Chiefs of Staff Rahm Emanuel and then Bill Daley as well as such core political advisers as Valerie Jarrett, David Axelrod and Robert Gibbs —would have a role in national security decision making that I had not previously experienced (but which, I'm sure, had precedents). -- Wars are a lot easier to get into than out of. Those who ask about exit strategies or question what will happen if assumptions prove wrong are rarely welcome at the conference table when the fire-breathers are demanding that we strike—as they did when advocating invading Iraq, intervening in Libya and Syria, or bombing Iran's nuclear sites. But in recent decades, presidents confronted with tough problems abroad have too often been too quick to reach for a gun. Our foreign and national security policy has become too militarized, the use of force too easy for presidents. Today, too many ideologues call for U.S. force as the first option rather than a last resort. -- On the left, we hear about the "responsibility to protect" civilians to justify military intervention in Libya, Syria, Sudan and elsewhere. On the right, the failure to strike Syria or Iran is deemed an abdication of U.S. leadership. And so the rest of the world sees the U.S. as a militaristic country quick to launch planes, cruise missiles and drones deep into sovereign countries or ungoverned spaces.
