President Obama said on the eve of a NATO summit meeting that U.S. needs to renew its partnership with Europe to boost up the NATO alliance.

In past year, the NATO alliance has been damaged by both U.S. arrogance and insidious anti-Americanism in Europe,” said Obama.

America is changing, but it cannot be America alone that changes, Obama told a crowd of about 3,500 students and local residents at the Rhesus Sport Arena in Strasbourg, France.

Obama arrived in Strasbourg Friday morning from London where he attended the G20 summit on dealing with the global financial crisis. The president said that he came to renew the partnership between Europe and the US.

He drew enthusiastic cheers when he announced to reduce nuclear stockpiles and close the Guantanamo Bay detention center, saying The United State does not and will not, torture.

The American-led invasion of Iraq in 2003 soured relations between the U.S. and some European countries, particularly Germany and France.

He repeatedly returned to his message that the U.S. and its allies must embark on a new era of cooperation.

We are confronting the greatest economic crisis since World War II, the only way to confront this unprecedented crisis is through unprecedented coordination , Obama said at a joint news conference.

Obama also urged European powers to bolster their military capabilities and shoulder more of the alliance’s burdens.
