“The one good concrete sign I see right now (other than all the goodwill talk) is the fact that they are not doing any tests.”
The declared they had completed testing months ago following successful completion of nuclear, ICBM and SLBM testing. IOW they have completed development of both warhead and missile platforms. Ego, they have moved to serial production of warheads and missiles. Hence the need to buy time forestalling any attack until their stockpiles have increased to numbers beyond what the US can defend against.
