1) There is absolutely no way you can know that. You are 100% wish-casting
2) Russia has 6000 nuclear weapons. To end the world for human civilization, only about 10 of those weapons have to work. 10/6000 x 100 = 1.6% That's right, if over 98% of ALL Russian nuclear weapons don't work (your premise) then human civilization still ends.
So your 2nd and 3rd paragraphs are wrong.
If the US or Ukraine (** wink-wink) were to try to take out Crimea - which Russia claims as part of Russia - Russia has said they may use a nuke. Yesterday a US drone with its transponder off was probing Crimea. So your first paragraph is also just wish-casting.
I have no idea who created our universe. I have the humble opinion that simple humans do not yet have the intellect to understand God even if God exists. I do know that we humans appear to be hell bent on destroying ourselves and this beautiful planet we were lucky enough to be born on. So I totally agree with your last sentence!!!
