It was like you described earlier. Last year and this year it is basically cumulating over multiple countries.
Swiss people are very upset with what is going on with their military spending in US. I do believe they will be serious about all other purchases from US.
Can confirm, as a Swiss person I am flabbergasted at how the federal government keeps pushing for the new fighter jets to be F35s, despite not only the US' currenr erratic behaviour in general, but how it has changed the terms of the purchase deal. Blows my mind, honestly.
But it worked well because it is military, they can manage long term projects without too much external interference and there is zero friction (if the head decides, the rest follows without asking).
In regular public administration, decisions can easily be overturned depending on results of each elections and it is not uncommon to face internal sabotage.
