This already happened. The US government cut off a judge at the international criminal court from her Office365 account because she was pressing a war crimes case against Benjamin Netanyahu.

It's the reason why in the last year you've seen multiple European governments very quickly build an escape hatch against US tech.

We all expect that you'll use our dependency on US services as a weapon, you've already done so, so we're phasing you out. It'll take decades to repair the lost trust in US digital services among the governments of Europe.

Excerpt from article 42 of the Italian constitution. This would cover, for instance, the entire eu-south-1 availability zone in AWS. I'm sure that other member states have their own provisions and you need to keep in mind that Google/Amazon/Microsoft employees in the relevant countries would predictably comply with local authorities, not obey a foreign power trying to collapse their governments.

If your power comes from saying "I own that", it's crucial not to enter complete hostility with nations, the only entities who can reply, "Says who?".

EU can live fine without US cloud services, and it's not very dependent on AI at the moment. If access would be cut off, companies would just switch to other solutions, which BTW are already there. The question is more how much time they would have to switch and adapt. An unannounced zero-day cut off would be of course harmful for a while (days, weeks, maybe months), but on most parts could be probably solved in a short timeframe for the important parts.

Also, EU (and probably most parts of the world) are already switching away at this moment already.

If they did that, their pension system (in huge parts built on stock) would collapse. The American tech market is largely saturated, and needs room to grow. The EU is a market of almost 500 million people with a lot of money. The US simply cannot ignore it.

What do you believe is so unique about US cloud providers? True, it's a de facto triopoly of American-incorporated businesses, but then what? It's not like computing is alien tech that only the US can own. The US doesn't even make the chips. It's commodity at scale with a bit of convenience sold at a steep premium.

This is not a flip the switch tomorrow hypothetical. The fallout of such an action would be huge for everyone, including the US stock market.

Here in Europe, every government and major corporation have recently added their dependance on US platforms to their risk management taxonomy. For the (unlikely) scenario you mention, for the scenario that their company/government somehow runs afoul of the US goverment and this is used as leverage, for espionage reasons, and for other reasons that may have already been in their risk overview (data privacy, compliance, etc) but were seen as manageable but are no longer so.

For some anecdotes: My former employer just moved off of AWS to a EU provider and will likely also move away from Google Cloud for their internal needs, my current employer has started evaluating moving off of Azure at the request of our clients (though they dismissed the idea of moving off of Office 365 internally), and my partner's company (a large corporate) has started prioritizing a transition plan away from AWS.

> Huge parts of the public and private sector could collapse.

temporarily yes, then EU will be able to build them on its own.

But what would also collapse is trust in all US companies, whole world will start working on their own solutions, no more AWS/GCP/Azure hegemony in the world. Everyone would close their internet, just like China did and develop own solutions

You can do that, once, if you want to trigger an avalanche of realignment away from the U.S.

Not only would you lose the 450 million odd EU customers, but the rest of the world will reconsider doing business with you as well.

> Huge parts of the public and private sector could collapse.

Today, yes.

The possibility of this, combined with how seriously Greenland was taken, means the EU is collectively saying "as a matter of urgency, we need strategic independence from the US".

This will take a while. Ironically, access to AI will make the transition much faster.

However, this is currently mutual interdependence: if the US actually cut off non-AI cloud to the EU, the US would screw over one of their major suppliers thus preventing them from supplying stuff, and leave itself entirely at the mercy of China. If it cut off AI to the EU, there goes a big market for tokens and the current data centre supply looks even more sketchy than its effect on electricity prices has already made it look. (But one bit of good news is that US electricity prices would come down).

Yes, think about that and how the shares would drop in an instant.

Good thing european governments and industries start to work on real technological and financial independence. It is high time for cutting ties with a country that is acting as irrational and self centered as the usa.

We would build our own alternatives. Russia is a much smaller market (120 million people) and they have their own tech companies.

And achieve what exactly? EU being dependent on US cloud services also mean EU being a big part of their revenue. Parts of EU public and private sector may collapse but they will also switch to their own alternatives, the broken trust and lost revenue on the other hand will definitely not be recovered by US companies.

It would hurt the EU more than it would hurt us and they're in denial about it.

Which is when we'd enter economic warfare between the EU and US, something which no one wants to experience. If that were realistically threatened, and we've seen motions in that direction, it's about political and economical survival and we'd see a massive loss of market for US tech.

> Imagine if the US, behind closed doors of course, threatened to cut off all cloud services

That would be the single best thing that could happen to the EU.

I think people would be surprised by how quickly European and international companies and governments can rid themselves of the American tech stack. They use this stuff because it's convenient, solid, and cheap, not because it's the only option.

> Huge parts of the public and private sector could collapse.

Yes, both in the EU and the US, initially. It would also force the EU to finally invest in its own tech stack and end the US's ability to sell software globally.

People seem to believe that America's global economic dominance is a law of nature that will never change, regardless of what the US does. But it's not. There is no American exceptionalism, other than what America worked for.

If you continually kick your customers in the face, they'll eventually stop being your customers.

That's why our relationship is ending.

It would hurt, for a while. Then people would wake up and slowly better solutions would appear. Not unlike post-Trump NATO. But the US would have lost its leader position and a large market.

I think the EU needs a kick under the ass to stop its comfortable inertia.

Not anymore :)

Humanity has lived for thousands of years without cloud and AI services. We can definitely live without those. In fact, considering the damage that is being done to the environment (and thus ourselves) in name of those services, we’d very likely be better off without them in the first place.

A large reason US services have such a presence in Europe is that their flagrant disregard for rules and the pursuit of profit at all costs gives them an unfair advantage. If those US companies cut off their services, in the long run the ones in the EU would have the room to expand within the rules. That’s the opposite of the doomsday scenario you’re describing. Though of course an abrupt cut would be momentarily disruptive, countries in the EU are already taking steps to reduce reliance on US services (for example: LaSuite).

Cloud services would hurt because of the data stored there. Suddenly being cut off your own data is obviously an upheaval.

It also shows how untrustworthy a partner is when this threat is thrown around casually. Also why talks of tech sovereignty are a lot more prevalent now.

If you brought that up 10 years ago, people looked at you as if you were a crank conspiracy theorist. Now everyone takes it seriously. Maybe a decade from now this will have been addressed.

AI services are a lot less important than you presume. Cut access to it and the workd keeps moving as usual.

The EU would counter that threat with the anti-coercion instrument. Shut Trump up really fast when he was last talking about annexing Greenland.

> Imagine if the US, behind closed doors of course, threatened to cut off all cloud services. Huge parts of the public and private sector could collapse.

I think the EU member states would declare it a matter of national emergency and nationalize the relevant assets, with every other country these American companies sell to taking notes and considering doing the same pre-emptively, providing a huge investment boost to EU tech companies (and almost certainly China) while tanking the US economy, and poisoning the ability of the Americans to sell to Europe for the next hundred years.

You don't win the opium wars by threatening to cut off the supply of opium.
