He'll control an unaccountable drone program, and the prison at Guantanamo Bay. His FBI, including a network of 15,000 paid informants, already has a record of spying on mosques and activists, and his NSA's surveillance empire is ubiquitous and governed by arcane rules, most of which remain secret. He will inherit bombing campaigns in seven Muslim countries, the de facto ability to declare war unilaterally, and a massive nuclear arsenal — much of which is on hair-trigger alert.
