未可乐观 meaning in Chinese

give no cause for optimism; there is no cause for optimism

In particular , when our comrades working in the red army are defeated in battle or encircled or pursued by strong enemy forces , they often unwittingly generalize and exaggerate their momentary , specific and limited situation , as though the situation in china and the world as a whole gave no cause for optimism and the prospects of victory for the revolution were remote
特别是我们在红军中工作的人，一遇到败仗，或四面被围，或强敌跟追的时候，往往不自觉地把这种一时的特殊的小的环境，一般化扩大化起来，仿佛全国全世界的形势概属未可乐观，革命胜利的前途未免渺茫得很。
