Being the first to cross the finish line makes you a winner in only one phase of life. It's what you do after you cross the line that really counts.
To this day I don't ever remember seeing a pet inside Moscow, I never saw anyone carrying a dog, or leading a dog. Err I finally saw a, a pet some years later in Kiev, so I thought that life must have been, different.
So you had to rev your engines, to beat the Russians and I think more than anything, if the Soviet team would win, or the Soviet athletes would win, you would see and hear and read about that. Quite frequently. So they would make a big issue of it.
