I think that is the wrong approach. North Korea is the result of what you advocate for, a people who do not know the possibility of other lifestyles. The complete isolation of a country is similar to locking up a child in a basement: It corrodes the mind and prevents escape for something better.

This isn’t to say that Russia, Israel, nor North Korea shouldn’t be impacted by their harmful characters. Instead, they should be treated like post-WW2 Japan, where outsiders force reforms. In Japan’s case, that was the dismantling of mega-corporation zaibatsu, ensuring democratic voting, removing previous leadership, reconstruction programs, and so forth.

It isn’t much different from tending a garden, where you both help and harm to ensure that the best plants get ahead of weeds.
