The U.S. death toll became 4,000 as 4 U.S. soldiers were killed in a roadside bombing in Southern Baghdad, late on Sunday evening.

As the Iraq war heads into it’s sixth year and the death toll continues to rise, President George W. Bush insists “lives were not lost in vain” and pledges to make sure of this.

He pledged to ensure “an outcome that will merit the sacrifice” of those who have died whilst serving in Iraq. Following a two hour briefing on U.S. diplomatic strategy around the world, President Bush said: “One day, people will look back at this moment in history and say, ‘Thank God there were courageous people willing to serve because they laid the foundation for peace for generations to come,’”

Milestones of this nature usually go unnoticed, however Bush decided to briefly comment on the losses albeit without taking questions from reporters.

As the Iraq war heads into another year and another milestone, President Bush is determined to prove the lives were not lost in vain and continues to insist upon its importance to America and the world.
