Russians and the US consider this unreliable because of the sheer number of missiles (thousands) they anticipate that will launched at each other in a crippling strike and from land, air, sea and undersea, not in our case where we are talking about a hundred or less. They would be quite confident about solitary missile launches that can and will be taken down.
The defense evolvement will consider all aspects of countermeasures because the BMD developing countries are also developing the strike missiles too so the endeavour will be to deliver a complete package in the end including mid course and even at early stage interception, with the final being the terminal stage interception.
An empty warhead? my contention is why would someone do that and risk massive counter strike of real missiles and that too when the window is small.
As for determining nature of warhead, as I said earlier will depend on the situation of the war...prevailing circumstances will determine that as for silo launching - sure it cannot be detected but our missiles are mostly platform based and again fueling of missiles are based on surveillance, if a massive strike is planned it most probably will be picked up.
How did you come up with the 10x figure?
As for taking down CMs, that a different topic and can surely be done along with the BM.
No , they do not consider it unreliable because of the number of missiles involved , its the built-in counter measures and MIRV which make them so . Sure , they risk an all-out nuclear war at even the slightest disturbance in the world arena concerning them . Actually , we aren't talking about a hundred or less , that is foolish to assume , the equation isn't 1 missile per nuclear warhead but several reserved for conventional warheads too .
Still , the attack evolves fast , that is a universal rule
The missile gets counter measure and the fight of catching up with others continues . Have you read about the new technologies incorporated in Shaheen 1A ? You can increase the kill probability by making multiple layers or firing several interceptors for one missile but we can decrease it by using BM/CM + dummies combination which are relatively low cost and in the long run , make this shield economically nonviable .
No , an empty missile . Which doesn't focuses on accuracy but rather than on mimicking the behavior of a real missile . The misunderstanding is an issue , I told you before , even if a Nasr carrying a conventional warhead is being launched , nobody knows what inside it .
Yeah , that is one of the indicators , sure . But still there's no way to make certain the nature of the strike , is there ? Submarine launched missiles aren't for First Strike .
A conservative estimate , a dummy doesn't cost much whilst the interceptor costs is in millions of dollars .
I am not denying that .
