As an adherent of the view that the Constitution requires congressional approval before the President can use military force (other than in certain circumstances of national self defense), I think the President’s decision to seek authorization from Congress was legally required. While Marty is right that presidential practice has at times been otherwise, I don’t think that practice should...

President Obama's decision to seek authorization for military intervention in Syria is a watershed in the modern history of war powers. At no point in the last half century at least has a president requested advance congressional authorization for anything less than the full-scale use of force. Foreign Policy's David Rothkopf gets it exactly right: Whatever happens with regard to Syria, the...

In a surprise announcement, President Obama announced today that he will seek congressional approval for his plan to launch military strikes against Syria.  This is a smart decision, both politically and legally, since it will force many of his congressional critics to reveal their preferences, and take a position on this very difficult issue.  If they approve the strike, the...

[John Quigley is the President's Club Professor Emeritus of Law at Moritz College of Law, The Ohio State University] It is hard to find a basis for justifying air strikes against Syria.

This week on Opinio Juris, the possible intervention in Syria  took centre stage. Julian rounded up statements by the UK, Russia and France on the legality of a military intervention without UN authorization, and declared that the doctrine of humanitarian intervention suffered a massive blow when the UK House of Commons rejected a resolution on military strikes. Deborah discussed why the...
