German media outlets Süddeutsche Zeitung, WDR, and NDR also cite the report, noting that Russian President Vladimir Putin appears intent on testing NATO’s Article 5 guarantees. The alliance’s mutual defence clause obliges member states to come to one another’s aid if attacked. The assessment suggests Putin may seek to challenge how seriously that commitment would be honoured.



Maybe. There’s no guarantee that every European nation would be on board with sanctioning the US in this scenario.
The Netherlands (where I believe they have the only manufacturing base of the machines that make advanced chips) might decide that it’s not in their best interest to cut the US off.
Anyways I hope this Greenland shenanigans dies on the vine and my silly scenario never comes to pass.
