The United States is not going to apologise for “mistakes” made during the 12-year war. The statement came amid claims by Afghan officials that the Obama administration offered to write the letter as part of an effort to keep a small number of US troops in Afghanistan well past the 2014 deadline to withdraw. "There is not a need for the United States to apologize to Afghanistan. Quite the contrary," said US National Security Advisor, Susan Rice. She also added that "no such letter has been drafted or delivered. That is not on the table."
