15 years for owning a gun

Compensation is irrelevant if the confiscation is involuntary.

Boris -

DF didn't make any caveat for threats justifying confiscation. He said he couldn't think of ANY circumstance.

He added some caveats, like violation of rights.

What's the difference? Perhaps he hauled them by truck across the border himself. Let's say he obtained all parts through purchase of willing suppliers.

It matters because he doesn't have the right to transport nukes over other people's property without permission, including national borders which involves property in 2 countries.
And since most property used for transportation is "public", he would need the public's permission. I suggest you remove the threat aspect of your scenario, it isn't needed and just convolutes the point you're trying to make.
