During the ill fated Spring of 2003, George W. Bush lost his focus upon the perpetrators of 9/11 and invaded Iraq. Two of the principle reasons used by the Administration to justify the invasion of Iraq were:
(1) Iraq was somehow involved in 9/11.
(2) Iraq (still) possessed Weapons Of Mass Destruction and were intent upon using such weapons against American interests, both at home and abroad!
Both of the principle claims used by the Administration to justify the need for America to invade Iraq were later found to be false. GW's mistake cost the American taxpayer $1 trillion, approximately 4,500 American lives and thousands upon thousands more who were injured, many of them seriously. This poorly conceived war proved to be a mistake of catastrophic proportions and eventually was a principle factor in the financial collapse that occurred in September of 2008 and beyond. Therein lies the legacy of GW's 8 year Presidency.
In 2008, a war weary American public elected a President who boldly proclaimed that he would end American involvement in Iraq. Less than 3 years after taking office, America's involvement in Iraq is finally over. Thank you Mr. President!
