Assuming there really was authorization from the Iraqi government, I don't have any doubt that the U.S. has the right under the international law to launch new airstrikes in Iraq.  But the domestic authority for the U.S. airstrikes is much more murky, and, as Ilya Somin argues here, Congress might need to authorize continuing military action. Jack Goldsmith goes through the domestic legal bases...

This week on Opinio Juris, we had some vigorous debate on the legality of Israel's "Operation Protective Edge" in Gaza. Kevin opened the week with the question whether Israel can cut off water and electricity to Gaza, and Janina Dill raised two concerns with the IDF's practice of using warnings. Julian commented on the Joint Declaration on the Gaza Offensive signed by over 140...

Under any view, the privilege of combatancy is key to the basic architecture of the law of war. It stands at the fault line between domestic criminal law and International Humanitarian Law, between impermissible killing and lawful belligerency. Simply put, the privilege of combatancy transforms, almost magically, what would otherwise be an unlawful act of murder into a lawful killing...

Since the recent al Bahlul en banc decision before the D.C. Circuit, I have been thinking a lot about the Common Law of War. As others have already analyzed in detail (Steve, Peter, Jonathan, Marty & Steve), the D.C. Circuit upheld Bahlul’s conviction for conspiracy but threw out his conviction for material support for terrorism and solicitation. Material support and solicitation...

A background paper for a High Level Review of Sanctions currently underway at the UN raises some important and interesting questions about the increasing "jurisdictional overlap" between individuals designated on targeted sanctions lists and international criminal courts.   In relevant part, the paper states: Increasingly, the reach of sanctions has gone beyond those responsible for initiating and supporting threats to, or breaches...

In two decisions (here and here) handed down this morning, the European Court of Human Rights has found that Poland violated its obligations under the European Convention of Human Rights for its complicity in the United States' running of a CIA black site and high-value detainees program on Polish territory. One of the cases involved al-Nashiri, who was prosecuted before a U.S. military...

The recent downing of Malaysian Airlines Flight 17, apparently by an anti-aircraft missile fired from within rebel-controlled territory in the Ukraine, has raised the specter that Russia is covertly (or not so covertly) supplying arms and assistance to the pro-Russian separatists operating within eastern Ukraine. Obviously, the facts here are somewhat contested and I have no insider or independent information...
