The new Russian defense system, if it is as good as bill, it is a copy of out patriots, with longer range and phase radar, will take down anything we fly. And seeing the rouge status of NATO.

Everything the Russians have fielded in the last 50 years has been in pairs or triplets, in the hopes at least one would work as advertised. Buying the initial system is one thing; getting technical assistance and spare parts is another they haven’t ever quite mastered.
