After prolonged internal debate, the Donald Trump administration seems to be nearing a decision on how to proceed in America’s long war in Afghanistan. Trump’s military advisers -- along with his national security adviser, General H.R. McMaster -- are said to be pushing a plan to send several thousand additional troops into that conflict. Can this “mini-surge” succeed? It all depends on how success is defined. If the goal is to decisively turn the tide of the war and force the Taliban to make peace, then the answer will almost certainly be "no." Yet if the administration seeks more modest but still meaningful goals in Afghanistan, a mini-surge may do the trick.
