WASHINGTON - A US soldier, who was wounded in 2004 in Iraq, has written a letter from his deathbed accusing ex-President George Bush and former VP Dick Cheney of unforgivable war crimes, and asked them to seek forgiveness for their sins. "I write this letter on behalf of the 4,488 soldiers who died in Iraq. I write this letter on behalf of thousands of veterans who have been wounded and on behalf of those whose wounds, physical and psychological, have destroyed their lives.” I am one of those gravely wounded," Tomas Young, who is paralysed, said in the letter. "I write this letter on behalf of those veterans whose trauma and self-revulsion for what they have witnessed, endured and done in Iraq have led to suicide and on behalf of the active-duty soldiers and Marines who commit, on average, a suicide a day," Young continued, acknowledging that he too has suffered from depression since joining the army. "I joined the Army two days after the 9/11 attacks. I joined the Army because our country had been attacked. I wanted to strike back at those who had killed some 3,000 of my fellow citizens," Young stated.
