> despite the fact that nukes will probably never be launched from aircrafts if at all

"if at all": that's deterrence. I don't think any nuke-able aircraft small-country customer intent is to launch, but you gotta have the ability to.

"from aircrafts": when you have no submarines/silos and carting ground launch platforms around is impractical for your country, aircraft is the only remaining option to display deterrence factors.

If the US need Belgium planes to launch nukes, well, europe is truly fucked anyway.

If the US had the French doctrine i.e. any army moving toward France's strategic assets will be targeted with a "warning" shot (yes, the warning shot is to be nuclear), but it does not, US nuclear force is for retaliation only. It will never be launched from planes in the foreseeable future. Which is more than the operational lifetime of F35.

No, this is bully tactics and frankly i really, really hope that Trump dissolve NATO so Belgium don't have to buy planes that can fly 30% of the time.
