美國對朝鮮核威脅強硬表態

The Trump administration has articulated a tougher approach toward North Korea in recent days, saying it has lost patience with Pyongyang's intransigence in the face of long-standing demands to curb its nuclear ambitions.

"Those who would challenge our resolve or readiness should know, we will defeat any attack and meet any use of conventional or nuclear weapons with an overwhelming and effective American response," Vice President Mike Pence said Wednesday aboard a U.S. aircraft carrier in Japan. That followed his comments Tuesday in Tokyo declaring the U.S. will not rest until it achieves the goal of a denuclearized Korean Peninsula. And at a stop in Seoul earlier, he said, "The era of strategic patience is over" — referring to the more muted Obama administration strategy.

Pence's visit to northeast Asia came as the president's national security adviser, Lieutenant General H.R. McMaster, told ABC News "all our options are on the table" in North Korea. However, McMaster expressed hope there would be no need for a military strike against the North.

In a pair of recent Twitter posts, President Donald Trump referred to the Pyongyang regime as a "menace" that is "looking for trouble." Taking a broad swipe at Obama's approach, he wrote, "The first 90 days of my presidency has exposed the total failure of the last eight years of foreign policy."川普政府近日對朝鮮明確表明了一種更加嚴厲的策略，表示在長期遏制朝鮮核野心方面，對平壤毫不妥協的態度已經失去耐心。

美國副總統彭斯星期三在日本的美軍航母上說，“那些想挑戰我們的決心或準備狀態的人應當明白，我們將擊潰任何進攻，對任何常規或核武器的使用，美國將做出壓倒性和有效的迴應”。此前，彭斯副總統星期二在東京宣佈，在實現朝鮮半島無核化目標之前，美國不會善罷甘休。更早前，彭斯在韓國首爾表示，“戰略忍耐的時代已經結束”，影射的是奧巴馬政府更爲低調的戰略。

彭斯對東北亞訪問之際，美國總統國家安全顧問麥克馬斯特中將告訴美國廣播公司，對於朝鮮問題“不排除任何選項”。但是，麥克馬斯特希望，不需要對朝鮮進行軍事打擊。

川普總統最近兩度發推，指稱平壤政權是“自找麻煩”的“威脅”。川普同時狠批奧巴馬政府的對外政策說，“我擔任總統這90天，已經暴露出過去8年外交政策的徹底失敗” 。
