According to spokesmen of a moderate wing of the Free Syrian Army (FSA), in November 2012 Nusra had between 6,000 and 10,000 fighters, which was 7–9% of the FSA's total fighters. Commentator David Ignatius for "The Washington Post" described Nusra then as the most aggressive and successful arm of the FSA. The United States Department of State stated likewise: "From the reports we get from the doctors, most of the injured and dead FSA are Jabhat al-Nusra, due to their courage and [the fact they are] always at the front line". On 10 December 2012, the U.S. designated Nusra a foreign terrorist organization and an alias of Al Qaeda in Iraq. That decision made it illegal for Americans to deal financially with Nusra. Days earlier, the American ambassador to Syria, R. Ford, had said: "Extremist groups like Jabhat al-Nusra are a problem, an obstacle to finding the political solution that Syria's going to need".
