Obama Wins Berlin Over

Barack Obama said Friday that persuading NATO allies to contribute more troops to Afghanistan could lead to U.S. troops cuts and help improve the U.S. economy, with reduced military expenditure being diverted into tax cuts to help middle class families.

"Part of getting that right is having the Europeans engaged and involved in this same battle that we're involved with," the Democratic presidential contender told CNN's Candy Crowley in Berlin, Germany, where he had addressed an estimated crowd of 200,000 a day earlier.

Obama's multi-nation trip, which has included stopovers in Afghanistan, Iraq and Israel, is aimed at bolstering his foreign policy credentials. The one-term senator has been criticized as inexperienced by Republican rival John McCain.

Obama was in France on Friday meeting with President Nicolas Sarkozy. His last stop will be the UK later Friday.
