Sure - but it would be ridiculous to expect the world to continue business as usual with a nation that has dedicated the past few decades to being as big of a nuisance as possible.
Given our administration's current views on Iran, and the Obama administration's similar views, it would have been trivial for Iran to be welcomed back into the international community.
Yet... they once again chose the opposite. So, today, that means no more Minecraft. Perhaps one day the population of Iran will have had enough of their government and make changes.
