US military official General David Petraeus said that there was "stunning potential" for Afghanistan, going on to say that "[t]here are a lot of ifs, of course, but I think potentially it is hugely significant." Waheed Omar, a spokesperson for Karzai stated that "it's very, very big news for the people of Afghanistan and that we hope will bring the Afghan people together for a cause that will benefit everyone." Analysts were less optimistic about the potential for a mining industry. Janan Mosazai, one such analyst, said that "I highly doubt it will be able to either properly manage these resources or use the riches to build a more peaceful and prosperous Afghanistan for all Afghans." Mosazai cited Nigeria as an example of a country that has seen increased violence as a result of abundant natural resources; in that case, oil.
