四面楚歌を英語でなんと言うか？

being surrounded by the songs of Chu on all four sides　といってもわかる人にしかわからないし、周囲を敵に囲まれた状態、being surrounded by enemiesのことかもしれないし、敵に包囲されて敗北は避けられないととればstaring defeat in the faceのことです。普通の会話での四面楚歌はnot a friend in the worldくらいの意味です。ニュース用語ではbesieged, beleagueredのような単語がよく使われます。

But turning that into reality was to take a heavy toll in human lives, for the Japanese were tenacious fighters. Battles raged between the carrier fleets in the Coral Sea, Midway and the Marianas, until the Japanese were driven to the last desperate resort of a nation staring defeat in the face - suicide attacks. But Banzai charges and Kamikaze raids could not stave off the inevitable Allied advance on Japan.
