Rhodesia was not perfect, it was a White minority ruled nation that was a product of European colonialism. But, it was prosperous, had been in place for many generations and it lifted up the lives of all its citizens. Rhodesia had integrated its schools and military and was in the process of transition to a true democratic majority rule. Agreements were in place for this with Henry Kissinger and the Ford Admin in the mid 1970's. And as others said, Rhodesia was the most modern, and developed nation in Africa until it was destroyed by communism. How?
Communist insurgents backed by Russia and China took steps to destabilize the Rhodesian government and were guilty of murdering white farmers in the countryside and committing other terrorist acts. Instead of assisting the Rhodesian government, the USA and UK abandoned them.
Queen Elizebeth was snubbed by Rhodesia when they declared their independence from the British Empire. She held onto a grudge for that reason. Jimmy Carter and his liberal Sec of State Andrew Young worked with Margarett Thatcher to stab the Rhodesians in the back. They backed out of the agreement and supported a total embargo by the UN of the Rhodesian economy including arms, and military aid. Only the Czechs and South Africans would help but this was too little to stim the tide of insurgents from Moz and Zambia backed by the Chinese and the Russians. It took years before Ian Smith was forced to throw in the towel. While not perfect the communist rule that replace the Rhodesian government was a disaster.
When Robert Mugabe was "Elected" President, he we president for life, because no free fair elections were ever held again during his rule. The country remains frozen in time in some ways with infrastructure now being over 50yrs old and starting to crumble. An old saying comes to mind that many of us should heed. "You can vote your way into socialism but you must shoot your way out of it." Today it is modernizing but where would it be today had a democratic republic been maintained instead of being wiped out.
Progressives are only socialist in sheep's clothing. They slowly, progressively change their nation by uncontrolled immigration, dependence of the lower class on social programs, and indoctrination of each successive generation with more liberal policy thinking thru control of the education system. Younger voters are naturally more liberal as they lack the life experience to have matured into conservatives. Many do grow up eventually but others never seem to wake up. I know and am friends with former Rhodesians as well as citizens of Zimbabwe who have left to find a better life free of poverty.
I just saw a meme today that said: "The Mouse Trap works because the mouse is not smart enough to ask why the cheese is Free" -- There is no free lunch or free government benefit. We all pay for it one way or another. Communism sounds great until you run out of other people's money.
