One could also argue it might accelerate progress. We chose to ban China from the ISS under spurious rationale. And this ultimately drove China to shrug and create their own space station, which they've just recently completed. If they had been allowed on the ISS it's very possible, if not exceptionally likely, that today that Chinese space station would not exist. And it's unlikely the ISS would have been marketedly improved by Chinese presence.

So excluding China from the ISS ultimately worked to expand the overall reach of humanity into space. I would predict the exact same will happen in various other venues, from semiconductors to movies. Necessity is the mother of invention, and globalism minimizes necessity. Minimizing necessity is good from a comfort/stability point of view, but not necessarily good from a progress point of view.

Another great example would be the space race. If the US and USSR had been on friendly and positive terms, it's extremely likely that the space race (which was not only a cultural battle, but a weaponization proxy) would not have happened. In other words if we'd been a more global society in the past, it's very possible man would yet to walk on the moon.
