“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.
I don’t say I trust them, however we can monitor their production and activities through satellite. This could all be a ruse, but what makes me feel good is the signs that President Trump is giving out. I trust him and he seems to be cautiously optimistic, therefore I am also.
