奧巴馬敦促加強導彈防禦系統以應對朝鮮威脅大綱

U.S. President Barack Obama is calling for a strengthened missile defense system in order to counter the threat of North Korea, which defied U.N. sanctions by conducting its third nuclear test.

Speaking Tuesday at the annual State of the Union address, President Obama vowed to take "firm action" in response to the test.

Mr. Obama's speech came just hours after the U.N. Security Council unanimously condemned the underground nuclear test, calling it a "grave violation" of previous international sanctions against North Korea's weapons program.美國總統奧巴馬敦促加強導彈防禦系統，以應對來自朝鮮的威脅。朝鮮無視聯合國的制裁決議，進行了第三次核試驗。

奧巴馬星期二發表年度國情諮文演講時，誓言將針對朝鮮核試驗採取“堅決的行動”。

在奧巴馬發表演講的幾小時前，聯合國安全理事會一致譴責朝鮮進行地下核試驗，並說這一舉動“嚴重違反”了先前國際社會針對朝鮮武器項目的制裁規定。
