WASHINGTON (AP) — A decade ago, the United States was touting Myanmar as an American success story. The Obama administration reveled in the restoration of civilian rule in the longtime U.S. pariah as a top foreign policy achievement and a potential model for engaging with other adversaries, such as Iran and Cuba. But today, Myanmar is once again an international outcast, facing a new wave of U.S. sanctions. A coup has returned the military to power and pro-democracy activists, reform advocates and journalists have been attacked and detained in a brutal crackdown. The collapse is not America’s fault, but it follows inconsistent efforts to nudge the Southeast Asian nation further toward democracy.
