Jack Goldsmith offers five thoughts today at Lawfare about the D.C. Circuit's Hamdan II decision.  I agree with two of his thoughts -- that the government is free to rely in future prosecutions on alternatives to material support (MST) such as aiding and abetting terrorism, and that (sadly)  al-Bahlul could be detained indefinitely if he is ultimately acquitted by his...

Christopher Stevens and three other Americans.  My condolences go out to the victims' families and the U.S. Foreign Service community, the Marines who guard them, as well as the local...

Having followed the terrorism litigation against Iran for years, I was fascinated to read of the recent legislation—Section 502 of the Iran Threat Reduction and Syria Human Rights--that creates a legislative fix for victims of one particular group of terrorist victims but not thousands of others. The law in question grants plaintiffs/judgment creditors in one and only one case—Peterson...

A guilty verdict was handed down against Taylor last...
