MONS, Belgium - NATO's supreme commander says the alliance ultimately will win the escalating war in Afghanistan, but will face more "bad days" along the way.

U.S. Navy Adm. James Stavridis says Wednesday he doesn't know whether the alliance will request troop reinforcements. European allies are increasingly reluctant to commit more soldiers to the eight-year fight against the resurgent Taliban.

Stavridis says he is awaiting recommendations later this month from Gen. Stanley McChrystal, the top American and NATO commander in Afghanistan.

Stavridis, the first Navy admiral to oversee NATO forces, is part of the new military and political team assembled by President Barack Obama to conduct the war. The group includes Anders Fogh Rasmussen, NATO's new civilian chief.
