U.S. President George W. Bush paid tribute to the British people on Saturday, two days after deadly bombings struck London's transit system, and reiterated his pledge that the "cause of freedom will prevail" against terrorists who are trying to shake the will of the free world. "The terrorists cannot shake our will," the president said in his weekly radio address. "America and its allies will act decisively, because we know that the future of civilization is at stake in this struggle, and we know that the cause of freedom will prevail." Bush went on Friday to the British Embassy to sign a book of condolence after returning from Scotland where he attended the annual meeting of leaders of the Group of Eight industrialized nations. In his radio address, Bush noted that the bombings took place as G-8 leaders were discussing how to fight poverty and HIV/AIDS, clean the environment and improve the lives of the world's people. "The contrast could not be more vivid between the intentions and the hearts of those who care deeply about human rights and human liberty, and the evil intentions and acts of those who rejoice in the death and suffering of the innocent," he was quoted as saying by The Associated Press. Bush travels to Quantico, Virginia, on Monday to deliver a speech on the war against terror and the strategy for winning it to men and women in the FBI Academy there.
