Yes, nothing is certain but I do think it wasn’t preordained – a White House which took climate change seriously, which wasn’t so invested in fossil fuel production, might have shifted the conversation to making nuclear safer because it would also reduce the even larger ecological footprint of coal and oil production. Reagan famously appointed a self-described “anti-environmentalist” and counted the dubious accomplishments of increasing strip-mining and opening up land for oil drilling so pretty much anyone would have been an improvement.
