We are already in a trade war and the only one that refuses to acknowledge it is the US. The US needs to embargo and deprive EU of the essential tech infrastructure they provide it. Just turn it off or brick it one day and leave the EU scrambling to catch up with 20+ years of stagnation and missing services and hardware.
Let's see how good it will be for the consumer when tech just leaves. Maybe then they'll change their regulations to something that works to enable technological progress and innovation.
