Oh, please. Let's not pretend that the 1980's didn't have divisive politics or that sensitive issues were non-starters for Disney. Even global political alliances didn’t stand in the way of considering various locations.
When the park opened, Germany was represented by a single pavilion, despite there being two Germanys split by one of the world's most heavily militarized borders, complete with a very well-known border wall designed to keep people *in* (as controversial as our current border wall discussions are, consider the difference between the perceived need for a wall designed to keep people out and one designed to keep people in).
The China pavilion was designed and built on the heels of the devastating Cultural Revolution, which destroyed countless artifacts, traditions, and cultures, but pales in comparison to the Great Leap Forward just a few years prior to that, which led to widespread famine and the death of tens of millions of people. The Wonders of China filmmakers were the first westerners allowed to film at many of the sites, and were among the first westerners allowed in the country following the Cultural Revolution.
There were serious discussions about creating a Russia pavilion, despite the ongoing tensions of the Cold War between the US and USSR. While those two countries aren’t exactly the closest allies today, they also don’t pose an immediate existential threat to each other as they did when the pavilion was being considered.
Up in Future World, they created the Universe of Energy with Exxon, while the Energy Crisis of the early 70’s was still fresh in the collective memory, but didn’t shy away from creating a fossil fuel-focused presentation.
The difference is that in the 80's, Disney had the cajones to have a bold vision and execute it. Today’s Disney is too worried about the quarterly earnings reports and placating delicate snowflakes to try anything even remotely daring. But it’s okay, because Disney-branded characters will keep me from having to think too much about the incredible and diverse world around me
