Actually I think Russia, China, etc. are well aware of our nuclear response times. What I think Hillary was doing was indicating to Putin that she is willing to play with the concept of nuclear war - that she's not afraid of going there, and that, therefore, he better watch out. She's like a 13 year old girl saying "I'll do it, I really will!"
What Putin sees is her horrifying level of immaturity, and therefore, insanity.
And he makes plans to defend himself from the clear and present danger she represents to Russia - and the world. And he's discussing that RIGHT NOW with the leaders of many, many other countries.
Hillary wanted to convince him she's serious.
She did.
“She’s like a 13 year old girl saying “I’ll do it, I really will!””
That’s because she has unresolved issues that began in childhood , and is in some sense still is a 13 yr. old girl. I’m very serious about that.
You may be right about her sending a message to Putin (although I think most of her thoughts center around “I am the best and I deserve to be President.”) and I also agree that Putin likely sees her as emotionally immature and labile, and dangerous on that basis.
