U.S. President Barack Obama, speaking early Wednesday in Afghanistan at the tail end of a surprise visit there, discussed how the war will end and promised a steady drawdown of U.S. troops, CNN reported.

Obama committed to pulling 23,000 troops out of the country by the end of summer and sticking to the 2014 deadline to turn security fully over to the Afghan government. He said that NATO will set a goal this month for Afghan forces to be in the lead for combat operations next year.

The U.S. president promised not to keep troops in harm's way "a single day longer than is absolutely required for our national security," but promised to "finish the job" and "end this war responsibly."

Hours after Obama left the country, the NATO-led International Security Assistance Force reported a loud explosion in the capital, Kabul. Earlier in his trip, Obama and Afghan President Hamid Karzai signed an agreement outlining cooperation once the U.S.-led international force withdraws in 2014.

据美国有线电视新闻网报道，美国总统巴拉克·奥巴马在行将结束突访阿富汗的行程之前，讨论了战争如何结束的问题，并承诺会逐步削减在阿富汗的美军人数。

奥巴马承诺，在今年夏季结束之前撤出23000名在阿美军士兵，同时恪守底线——2014年年底之前，将防务全部移交阿富汗政府。他还表示，北约本月将制定目标，让阿富汗军事力量从明年起，在战斗中担任领导角色。

奥巴马总统还承诺不会让美国驻军受到危险，“不会让他们在完全确保美国国家安全的情况下多驻外一天”，但保证会“结束在阿富汗的任务”，并“负责任地结束这场战争”。

奥巴马离开后的几小时后，北约为首的国际安全部队报告说，首都喀布尔出现巨大的爆炸声。奥巴马此行较早时候，还与阿富汗总统哈米德·卡尔扎伊签署了协议，为2014年美国为首的国际部队撤出以后的合作进行了规划。
