War brewing on the latest front line against terrorism in Mali African and Western powers are already in disagreement over the timing and goals of a military strike. Also unclear is whether regional African forces are strong enough to defeat well-armed militants in desert terrain the size of Texas without help on the ground from Western armies. Johnnie Carson, U.S. Assistant Secretary of State for African Affairs, said this week that "the military concept proposes an Africa-led effort, but several key questions must be answered to ensure that this effort is also well-planned and well-resourced." Nevertheless, after months of hesitation, the momentum for a military intervention has surged in the region and among Western powers, as the radical Islamists and al-Qaeda militants have deepened their grip over the north. Analysts and U.N. officials say that any military strike is still months away, but the United States and France are playing an active diplomatic role in it and encouraging African nations to take the lead - a model used most recently in Somalia, where Islamist radicals also seized much of the country. Last month, the Economic Community of West African States (ECOWAS) approved a 3,300-member force for northern Mali. Thousands of Malians have fled to this capital to escape the Islamists" brutal rule, and many say military action is the only way to liberate the north. "It's the only solution," said Aziz Maiga, a 27-year-old rapper who recently left the north. Negotiating with the Islamists will not work. The American role has intensified since U.S. officials implicated al-Qaeda in the Islamic Maghreb - the terrorism network's North and West Africa affiliate known as AQIM - in the September assault on a U.S. mission in Libya that killed U.S. Ambassador J. Christopher Stevens and three other Americans. AQIM is one of the three major groups that now control northern Mali. In a telephone interview, a senior Islamist leader denounced the United States, declaring that its people are "against Islam" and that superstorm Sandy was "a punishment from God." If the Western countries send troops, that will be fine. We are prepared for war," said Oumar Ould Hamaha, the military leader of the Movement for Oneness and Jihad in West Africa, known as MUJWA, which is an offshoot of AQIM. If they don't come here, one day we will attack them. If we cannot do this in our time, our sons and the next generation will attack the West.
