More like sticking your fingers in your ears and ignoring the evidence that doesn't fit with your world view.

Dude, your evidence is flawed

you want to prove that green color is better then red, so you put a rat in a green box, a rat in a red box, then you starve the rat in the red box and give a ton of food to the green rat.

Then like a "genius self claimed scientist" you claim to prove that this is a valid experiment that proves that green is better then red.

Really. Why don't you go through all 40 counties one by one and explain why it's a flawed experiment that proves nothing?

You've made up your mind without looking at the evidence, as you've already demonstrated your ignorance of history, and somehow think that qualifies you to reject all of it - without having even considered it. You've proved my point rather nicely I think.

I done it already for Korea , N Korea suffers from external interventions like sanctions, S Korea received a lot of money from US. So it is not a clean experiment.

Would be more simple if you find the perfect example from those 40 and let's talk that one.
