The Washington Post reports the recent US assault on the Afghan area of Marjah is a prelude to larger military campaigns. Senior Obama administration officials say the United States has begun initial planning for a bigger, more complex offensive in Kandahar later this year. Eleven thousand US and Afghan troops fought in Marjah, making it the largest US-NATO military operation since 2001. The city of Kandahar is ten times larger than Marjah.
