They were already burdened with maintaining thousands of these nukes on 24 hr duty based on the philosophy of mutual destruction. Also, ABM tech was not matured enough to shoot down an incoming warhead at a few KM/Sec speed.
They realised that that producing ABM and Offensive system had got a life of its own as both parties got on developing ABM and BM to out do each other and it got unsustainable.When the relation got better they signed the ABM treaty restricting ABM deployment to one site. The 1972 ABM treaty has been the corner stone of all subsequent arm limitation agreement till US unilaterally withdrew from it in 2002
So, what is happening now is reducing the number of warheads, at the same time seriously pursuing ABM deployment (vice versa of what was happening in the past). In that sense, these two issues (ie., Nukes and ABM development) are becoming more and more detached from each other. I agree with you that in he past, these two were linked, mostly because of economics.
Just the contrary in the new START it does not change the original preamble that offensive and defensive system are interrelated to quote directly from new START text
link
Recognizing the existence of the interrelationship between strategic offensive arms and strategic defensive arms, that this interrelationship will become more important as strategic nuclear arms are reduced, and that current strategic defensive arms do not undermine the viability and effectiveness of the
strategic offensive arms of the Parties
The key operative word is any defensive system should not undermine the offensive system effectiveness and Russia has added a withdrawal clause to move out if defensive system undermines offensive capabilities. ( something that is available to US if it feels like wise )
So the relation is there between offensive and defensive system , atleast for the two parties of START treaty it is part of the entire deal
If you take the case of Japan or any other non-nuclear nation (you can also take Israel, if you ignore their nukes and the fact that most of their projected enemies are non-nuclear states), then I would consider that these two things are unrelated. The only relation I can see is that, if the enemy is a nuclear state, then the 'receiver' nation would seek the most advanced system available.
Japan only concern is NoKo which has very few nukes and Israel too has concerns on Iran nuke , Israel is itself a covert nuclear power there is no doubt. More every US provides security guarantees to these two states
Nobody is claiming that the systems fielded so far are fool proof and cannot be penetrated at all. There is constant improvement going on and someday you may find that these systems have matured enough to shoot down most of the incoming warheads
If that day indeed comes then our offensive system and consequently deterrent will get blunted as well.
The fact is BM has progressed and will continue in that direction and ABM will have a life of its own.
More every the exchange ratio and economy of ABM vs BM race is very favoured with the latter assuming even if ABM remotely works as advertised in real environment.
Agree..that is why developing an ABM system is much more complex and we must complement our scientists for having reached thus far. Support them, and they will be able to improve upon the existing system. OR, Buy foreign maal and kill the whole ABM research in its infancy.
Depends on how well GOI will support such ABM research , right now its a honeymoon period for ABM and scientist has indeed done well , but there is much greater strategic impact beyond the sucessful test of ABM , once the parties like Pakistan and China react to our development in their own way GOI will realise the impact and the fertile ground that will sustain an uncontrolled arms race its very early days though.
Ofcourse the other extreme view will be we can sustain longer then Pakistan so lets continue with this race as it favours us.
That is not a good point...how can you design a system which is effective on conventional BM and fail on Nukes? Who will design a BM to deliver conventional weapons (except SRBM, which anyway an be shot down with existing technology? We are interested in a BMD which can shoot down long range nuclear missiles with a good probability of kill.
How does one verify the impact of Nuclear Warhead/Missile with ABM , how do we ever know that a nuclear blast and EMP impact will ever keep ABM operational or partly/fully/optimally ? all the test done with ABM is only with conventional warhead
