European leaders and top diplomats hailed President Barack Obama's speech defining the new U.S. strategy in Afghanistan, but few countries were forthcoming Wednesday with pledges of fresh troops.

French President Nicolas Sarkozy commended the speech as "courageous, determined and lucid" but stopped short of offering more soldiers from France, the fourth largest contributor to NATO's Afghan effort.

In neighboring Germany, Foreign Minister Guido Westerwelle praised Obama's speech as supporting Germany's position that a political solution for Afghanistan backed by military support was the only way forward. Like France, Germany indicated that troop increases will not be discussed until after a London conference on Afghanistan in late January.

Speaking just hours after Obama announced the deployment of 30,000 fresh U.S. troops to Afghanistan, NATO chief Anders Fogh Rasmussen said in Brussels that European and other U.S. allies will contribute more than 5,000 more troops to the international force in Afghanistan.

Rasmussen did not specify where the troops would come from and how many would be from Europe _ and reluctance for major new troop contributions was palpable Wednesday across the continent.

Westerwelle praised Obama for making clear there must be an end to the mission.

"We agree with the U.S. president, that there cannot be only a military solution, but what we need is a political solution that is supported by the military," Westerwelle said.

He and his French counterpart, Bernard Kouchner, said their countries remained committed to helping build up and training the Afghan police force.

Of the major European continental powers deployed in Afghanistan, only Poland indicated a solid willingness to send more troops. A Polish official said the government will likely send 600 reinforcements to beef up its existing 2,000-strong contingent in Afghanistan.

Government spokesman Pawel Gras said the decision still needs approval from Prime Minister Donald Tusk's cabinet and from President Lech Kaczynski, the supreme commander of the army.

Most European nations appear willing to keep current troop levels for now, but they all want to see an exit strategy.

The U.S. now has 71,000 troops in Afghanistan, while other NATO members and allies collectively have 38,000 service members there. With the added reinforcements, the international forces will grow to more than 140,000 soldiers.

The Afghan army has about 94,000 troops, and is slated to expand to 134,000. The Afghan police number about 93,000 members.

The U.S. and Afghan forces face an estimated 25,000 Taliban insurgents.
