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.

據(jù)美國有線電視新聞網(wǎng)報道，美國總統(tǒng)巴拉克·奧巴馬在行將結(jié)束突訪阿富汗的行程之前，討論了戰(zhàn)爭如何結(jié)束的問題，并承諾會逐步削減在阿富汗的美軍人數(shù)。

奧巴馬承諾，在今年夏季結(jié)束之前撤出23000名在阿美軍士兵，同時恪守底線——2014年年底之前，將防務全部移交阿富汗政府。他還表示，北約本月將制定目標，讓阿富汗軍事力量從明年起，在戰(zhàn)斗中擔任領(lǐng)導角色。

奧巴馬總統(tǒng)還承諾不會讓美國駐軍受到危險，“不會讓他們在完全確保美國國家安全的情況下多駐外一天”，但保證會“結(jié)束在阿富汗的任務”，并“負責任地結(jié)束這場戰(zhàn)爭”。

奧巴馬離開后的幾小時后，北約為首的國際安全部隊報告說，首都喀布爾出現(xiàn)巨大的爆炸聲。奧巴馬此行較早時候，還與阿富汗總統(tǒng)哈米德·卡爾扎伊簽署了協(xié)議，為2014年美國為首的國際部隊撤出以后的合作進行了規(guī)劃。
