八、彝海结盟知识要点?

一、“彝海结盟”是信仰的胜利,弘扬红军长征精神,就是要把信仰的旗帜举过头顶,让我们的方向更加笃定。长征途中,面对国民党的围追堵截,面对异常严酷的自然环境,红军之所以能够始终保持顽强的意志、昂扬的斗志和乐观的情绪,靠的就是对革命理想的执著追求。

坚定的革命理想信念不仅是红军屡克强敌、战胜艰险的强大精神支柱和力量源泉,也是宣传革命、发展革命的重要法宝。

正是红军对理想信念的执着追求,让彝族人民看到了忠诚信仰和真情厚谊,才有了“彝海结盟”,有了“中国彝民红军沽鸡支队”。当前,国内外形势继续发生深刻变化,各种敌对势力加紧对我西化、分化,各种思想文化也相互激荡,尤其需要像红军那样牢固确立坚定的理想信念和崇高的价值追求。

西昌航天作为中国航天的重要力量,肩负着挑国之重担、铸国之重器的神圣使命,弘扬长征精神,更必须高度重视补精神之“钙”、铸强军之“魂”,用中国特色社会主义理论体系武装头脑,用民族精神和时代精神鼓舞斗志,引领航天官兵始终坚持理想信念不动摇、革命意志不涣散、奋斗精神不懈怠,为党的事业努力奋斗。
