返回式卫星、宇宙飞船的军事意义
人造地球卫星以第一宇宙速度（7.9公里／秒，or 23 MACH）飞行，并按预定轨道返回地球，完成设定科研任务。目前只有少数国家掌握这种技术。
返回式卫星、宇宙飞船的军事意义不言而喻。试想 － 如果将核弹装在这类太空飞行器上，让它变轨返回某地、引爆核弹。战争结束！

Simple, but devestating to human beings. Therefore, a war between the giants is not likely to take place unless they want to destroy the Earth!
However, a local regional war(s) is still happerning. A potential war cross the Taiwan strait is evident, the continuation of the China Civil War that started in late 1940s. That war has divided the nation for 70 years so far. Such the divided situation is unbearable for all people in China Mainland and cross the strait, that shall urge a reunification campaign, possibly via force, to come in soon. There is No doubt that this is the top interest of China.
