The Irish famine wasn't pretty either. I hold the Brits responsible for 1.5 million deaths there.
The Irish population collapsed from deaths and migration.
The population of Ireland today is still less than it was in 1840.
There were starvations all over the world, all over the history. Bad harvests often resulted in starvation epidemics.
The Stalin era starvation was special, because it was artificial. There were plenty of food available. Stalin used hunger to punish the population. He forcibly confiscated the food, wasted it, assigned it to desirables and even exported it.
I do not believe English confiscated and exported potatoes out of Ireland!
