Legal and policy developments affecting war, peace, and related civil liberties interests have come quickly in the new Trump administration. These involve immigration and the role of courts in our democracy, the ongoing war against the Islamic State in Iraq and Syria, targeted killing of terrorist suspects, security implications of climate change, cyber warfare, and NSA spying on Americans' email and phone calls. In the fall of 2017 we will focus on these developments as we address international and domestic authorities for the use of military force, intelligence gathering at home and abroad, the detention and interrogation of terrorist suspects, homeland security, espionage, and the protection of sensitive government information.
