令人恐惧的空军报告，警告中俄超音速导弹也许会威胁美国
The United States is falling behind in the race to develop hypersonic weapons, experts have warned.
In the last month alone, both China and Russia claimed they’ve test fired high-speed missiles that could destroy targets hundreds of miles away.
And according to a new study from the Air Force, the ‘relatively leisurely pace’ of US hypersonic developments leaves the country vulnerable to such attacks.
有专家警告，在超音速武器的研发竞赛中，美国正在落后
就在上个月，中国和俄罗斯称已经试验了高速导弹，可以摧毁几百英里外的目标。
根据空军的一份新研究，步伐相对较慢的美国超音速导弹的发展，使得国家容易受此类导弹的攻击。
Hypersonic missiles move at more than five times the speed of sound and can evade detection and defensive tactics with frequent manoeuvres and by travelling along the edge of Earth’s atmosphere.
In the new report, produced by experts for the Air Force Studies Board at the National Academies of Science, the committee concluded that the US may face a threat from this ‘new class of weapons,’ according to the the Washington Free Beacon
超音速导弹的速度超过5倍音速，导弹在地球大气层外缘飞行，可以通过频繁的机动，躲开目前的导弹拦截系统。
美空军研究委员会的专家撰写了这份新报告。据“华盛顿自由灯塔”报道，该委员会得出结论，称美国也许会面临这种新武器的威胁。
‘The People’s Republic of China and the Russian Federation are already flight-testing high-speed manoeuvring weapons (HSMWs) that may endanger both forward-deployed US forces and even the continental United States itself,’ an executive summary of the report explains.
‘These weapons appear to operate in regimes of speed and altitude, with maneuverability that could frustrate exsting missile defense constructs and weapon capabilities.’
报告指出，中国和俄罗斯已经在试飞能够危及前进部署的美国军队甚至美国本土的高速可机动武器。

It doesn't matter who's got what, once one releases a nuclear rocket everyone will set there's off, and it does not matter what,Russia,Japan,China, America etc says to there people ie what they should do in case of a nuclear attack. No one will survive, The shock to the world will knock it off its axs. we need people power to tell the few hundred thousand that control us ( the millions and millions ) would like to live a long and natural life and them not to decide when were going to die.

谁有了什么东西，并不重要
关键是，一旦有人发射核导弹，大家都会跟着发射
俄罗斯、日本、中国和美国等国家对本国人民说什么并不重要，关键是一旦发生核战，没有人能幸存下来

Don't be fooled. The 'China and Russia' threat is being faked by US defence companies in a desperate effort to get their government to fund the usual buying spree.

别被骗了
所谓的中俄威胁是美国军火公司杜撰出来的，为的是让政府多买武器
