tbh US made a choice for them long ago.

To be clear: the cause here is decades of mismanagement.

Just so we're clear: fresh water is shifting location ... when it comes to the total available, it's increasing. There are many more locations were humans can now live where they couldn't a century ago, not less.

The issue is not that we can't live anywhere. The earth is greener than before. The issue is that there are a small number of locations where humans can't live anymore, especially not without good water management. Obviously, people don't want to or can't leave, and some of the locations that didn't use to, but now really do require proper management have a LOT of people.

Teheran has more water than a century ago. But more does not mean infinite.

Nuclear program, ballistic missile program, drones, establishing and supporting multiple proxies in the region.

For a fraction of what they spent on that they could’ve have desalination plants in the Caspian Sea and a water way capable of providing water to their capital.

Yeah, there's something about allocating all of your water to those pesky Shahed drone factories for Russia instead of your civilian needs.

Fairly sure that's a typo, or he misspoke, given the sentence immediately before says "per year".

Not to mention the permanent destruction of your drained acquifers, which means you can't go back even if you wanted to, because that's what's causing the sinking in the first place.

There are, they want a more secure capital from which they’ll be able to continue operating if a civil war breaks out.

Moving a capital is bureaucratic. Setting up new offices does sound a lot cheaper than engineering a new water pipeline for millions of people across 300 miles.
