大敌当前 be confronted with a formidable enemy
be faced with a formidable foe
- 大敌当前, 我们必须加强团结。
- 全球变暖大敌当前,不只政客对树木的感情持续升温。
Amid fears of global warming, tree hugging is on the rise, not least among politicians. - 大敌当前,我国的人民、领土和利益正处在极度危险之中,我们对此决不可稍有懈怠。
Hostilities exist. There is no blinking at the fact that our people, our territory, and our interests are in grave danger.
