India's BMD will be useful in this way:before launch a ballistic missile to New Delhi, China first called India, telling them, when the missile will be launched, from exact where it will be launched to India, what type of the missile will be, DF 11? DF 16?? and what is the speed of the missile. etc, once Indian learned all of these data, then Indians thanks China for let them know, and tell China just a minute, since then India will need to  prepare to launch PAD by first putting  liquid fuel into that anti missile (liquid fuel cannot be stored inside missile for too long, so it needs to be added each time just before launch) and, then India call back China, saying, it is OK now, you may launch your missiles, and tell China, you cannot use missile with MIRV，that will be cheating,  then wait for the time that China will launch the missile.other than that, BMD will not work.with this BMD system, Indians can sleep soundly and dream all wonderful things not worry about anything in this world, since there will be always next life which should be much much better than this life.

印度反导系统只在这样的条件下有用：

中国在对新德里发射弹道导弹之前要先给印度打个电话，说，嘿，三哥，我们要对新德里发射弹道导弹了，时间是明天早上8点整，一分不差。我们的发射点是多少多少，一米不差。我们用的导弹是什么，速度多少，都告诉印度。印度听了说，好好，知道了，我们马上准备，先要拉来大地高空反导导弹呱唧呱唧往里加液体燃料，加完了一看，早上7点了，还有1个小时，给中国打个电话，说，行了，你们可以发射了，但是不许用有分导弹头的，要不是欺骗。
