Our risk of all out nuclear war with Russia is very slight today. Our economic ties are growing daily. Russians are allowed to freely travel here and see the truth of America.
China on the other hand is a different story. At this time it is not a significant nuclear threat. In time it may well be. We have plenty of time to adjust our nuclear strategy based on their actions as time goes on. As Russia becomes closer to America it will further pressure China. In time I wouldn't at all be surprise if Russia has more of their weapons aimed at China than any other country.
The signs are there if you know what you are looking at. I study history and military philosophy as a matter of personal interest; the parallels between today and 1941 are frightening. Read Sung T'Su's "The Art of War", find out how you really beat your enemy, and it isn't technology, friend.
I cannot change your mind about the future, if you think all is well, then go back to sleep. Maybe, just maybe, you might want to consider possibilities other than a bright sunny future...the answers are there if you want to see them.
