Many years ago in the so called,"cold war", we had many contacts on amateur radio with stations across the world including many stations that, at that time, were in the USSR. Some of my best QSL cards are from those years.
I would like to think that these QSOs helped to break down barriers between people. Amateur radio has no interest in politics and never should. We can be black, white, yellow or even green, male, female or in between, left wing, right wing, capitalist or communist. It matters not. We are all just humans with an interest in radio.
