U.S. extra troops

hi, last Friday, i read an article about U.S. troops. George W. Bush has decided to send about 21,500 extra U.S. troops to Iraq. the purpose of this is "secure Baghdad." his new strategy will be better to resolve the Iraq problem than the old strategy, he thinks. i think, however, his new strategy will improve nothing. just think, who are the U.S. troops? they are American young armies!! i suppose this new plan will lead to an increse of American victims.
