I see the same happening with choices about other suppliers. The EU is a very large trading partner to the US and what is happening right now is unprecedented in the last 75 years or more. The damage to our future world order is incalculable and the fact that it all seems to be by design bothers me greatly.
The lyrics of Alan Parson's 'Children of the moon' have been spooking through my head lately.
An extreme and inaccurate statement. The US is still party to NATO Article 5, meaning the blood of our young people is pledged to be shed to defend, say, Estonia. That has not changed.
What has changed is the US has become more realistic and up front about the limitations of its reduced military. It’s not healthy, for the US /or/ Europe, to indulge the imperial fantasy that US forces in Europe (token deployments in Germany and Poland) are sufficient to defend against Russian attack.
Trump is not the first US president to push Europe to do more of precisely what it is doing here (spend its own money on defense). Being clear about limits is what a reliable ally does.
Europe ordering an Airbus AWACS instead of Boeing now that the US stopped subsidizing them is not surprising nor does it mean the sky is falling.
What changed is the US President saying things like, he will encourage Putin to invade countries not spending so much on military.
What also changed is the US President threatening members of the EU militarily over greenland for example.
Reliable allies don't really do that.
(you probably do not realize the shock Denmark felt over this, that went deep and the change will not happen over night, but it will happen)
The president has repeatedly been vocal about the US leaving NATO as a possibility.
If I were the EU, I certainly wouldn't be counting on the US honoring any of its agreements and I'd be planning with the assumption that they will not join a NATO response.
