briefly put, the 'cold war', which is opposite to a 'hot war', was the usa, europe, et al, to the chinese (under mao) and russia (originally under stalin). this disagreement of wills and ways began way before WW2 but was stalled due to the axis and WW2. it originally began just after the red russians overran the russian front in 1917 but that's another story. anyway, and to wit, this cold war stayed a , pardon the pun, hot item for a prolonged time ending somewhere around the late 1980s. it's a long time, to some needless time wasted. i do believe most of this cold war time was instigated by all three govts to make their defense budgets unusually large and the munitions spending overweight. the real people caught in the middle were as curious about each other and found, after the 1980s, that they had way more in common than expected. i lived through it, and i can tell you, what a waste of time and space. the russians, chinese and usa/european people loved their kids, life and future in equal parts. glad it's over. want to know something totally freaky? check out the bomb shelters and the hollywood movies made during that time. paranoia for sale (and bought). silly, silly little men. p.s.: yeah, nuclear weapons were waved at each other but, glad to say, it became a 'my bomb is better and bigger than yours' thing. like i said, silly, silly little men.
