The US has military bases all around Europe from which they would be able to do actions to keep NATO from mobilising.
In 2024 I spent a day protesting outside the Swedish parliament against US base also in Sweden.
We warned about Trump probably winning the US election and how unpredictable he is, but the proponents disregarded all our arguments: "Trump being president again? Pfft.. That will never happen", "Provision for US leaving NATO? Pfft. They won't", "Rule against nukes on Swedish soil? Pfft. The US are our friends and will respect our wishes.". The vote passed, and here we are.
