Hmm thats funny, according to NATOs website there are coalition troops boots on ground in somalia currently. And the US does not have conventional troops on ground, but I wouldn't be suprised if they do happen to do UAVs etc or lend help for operations as is the usual game plan with their intelligence community.
NATO is an active and leading contributor to peace and security on the international stage. Through its crisis management operations, the Alliance demonstrates both its willingness to act as a positive force for change and its capacity to meet the security challenges of the 21st century.
Since its first military intervention in the Balkans in 1995, the tempo and diversity of NATO operations have increased. NATO has been engaged in missions that cover the full spectrum of crisis management operations ? from combat and peacekeeping, to training and logistics support, to surveillance and humanitarian relief. Today, roughly 135 000 military personnel are engaged in NATO missions around the world, successfully managing complex ground, air and naval operations in all types of environment. These forces are currently operating in Afghanistan, Libya, Kosovo, the Mediterranean, off the Horn of Africa, in Iraq and in Somalia.
