Incorrect Info......You are talking about 90's and now it's 2011.
I doubt that there is more investment in ABM systems today than was in the cold war days.
The kind of ABM systems you are taking about might shoot down an ICBM on papers but a realistic ABM system is not operational today nor so it seems to be in foreseeable future due to lack of investment and understanding that MIRved ICBM are simply just not possible to shoot down with current and near future technological level.
