According to Yahoo! News:
The nation can best honor the dead by “defeating the terrorists. … and by laying the foundation for a generation of peace,” Bush said.
Quite true indeed.
We pay tribute to the sacred memory of all the brave and selfless men and women who have made the ultimate sacrifice for the safety and protection of The United States, becoming effectively martyrs in the American Cause. We also pay tribute to those men and women who have pledged to defend The United States by fighting and, if necessary, dying for them. We honor past, present, and future defenders of The Republic, true heroes that you all are. The people live in freedom because of your sacrifices, dedication, and vigilance.
May God bless you all, and may we Americans never forget you. Because you gave your all every day of the year, every day is Memorial Day.
