特朗普释放美伊局势缓和信号：更倾向协议而非战争。美国总统特朗普：来自假新闻媒体的众多报道一 直在流传，声称丹尼尔·凯恩（Daniel Caine）将军，有时被称为拉辛（Razin），反对我们对伊朗开战。 这些报道并未将这一海量信息归于任何人，且百分之百不实。凯恩将军和我们所有人一样，不希望发生 战争，但如果决定在军事层面与伊朗对抗，他认为我们能够轻易获胜。他非常了解伊朗，因为他曾负 责"午夜之锤"行动，打击伊朗核项目。所有关于可能对伊朗开战的报道都是错误的，而且是蓄意为之。 我是做决定的人，我更愿意达成协议而不是打仗，但如果不能达成协议，对伊朗及伊朗人民来说，那将 是极其糟糕的一天。非常可悲，他们伟大而美好，这样的事情本不该发生在他们身上。 【美股】截至收盘，道指跌821.91点，跌幅为1.66%，报48804.06点；纳指跌258.80点，跌幅为1.13%， 报22627.27点；标普500指数跌71.76点，跌幅为1.04%，报6837.75点。贵金属、有色板块领涨，应用软 件、信息技术服务跌幅居前，IBM(IBM.US)大跌超13%，创2000年以来最大单日跌幅，此前人工智能 (AI)初创公司Anthr ...
