let me tell you some simple maths and world politics:
1. we can easily build, deploy and fire thousands of such rockets. they are cheap, they don't need to be reliable, they don't need to be accurate. we couldn't care less about your "missile" defense system because there is no way to defend all of them. on the other hand, your missile that can travel 5000km is way too expensive. how many of them you have?
let me honestly tell you this: China has less than 100 such missiles.
2. you can't first a long range missile with nuke head first, that is suicide. let's say you take out entire beijing successfully, then what is next? oh, yes, nuke fight back from our JL-2 missiles, from our mobile launch sets in rural China.
3. the above is based on the assumption that the missile did launch successfully and can reach China. is that assumption always true?
still remember the christmas launch diaster? whether new delhi is willing to risk using its own nuke to hit india due to such failure?
4. check mid course anti ballistic missile test. two nations can do it: US and China.
我的父辈,包括我的同辈,每天都在努力工作。34年来,你我两国经济、科技、军事的差距已经拉大到了不可比拟的程度。关键问题何在?一个人两国人均智商,一个人两国文化,汉人勤劳务实,阿三懒惰吹牛。
the most funny thing here is to listen some indian members to tell me that they have nuke missiles.
