The problem with applying that part of game theory here is it makes several assumptions.
The biggest is that the bigger party are playing for maximisation, rather than just to "win". That is very much not the game with trump.
The second is the assumption that there is only 1 game in play at a time. America could cause devastating economic damage, if it went full tantrum. Europe has noticed how vulnerable they are to that sort of action. They need to patch the holes before playing hardball.
Under these assumptions, taking fairly meaningless hits to buy time makes sense. Pull the wolf's teeth, before challenging it to bite you.

It's less based on the capacity, and more on how much time is likely a premium.
E.g. motorway services are more expensive, since people need the power and want to get back on the road. It's exactly the same logic as the price of petrol there.
