The thing which is exceptional is the amount of money and effort spent on defense by America compared to NATO allies or the rest of the world. Roughly 2x to 3x on a per capita or percent GDP basis of any European nation. More in total than the next 11 nations combined.

It is not through awesomeness but simple resource dedication which buys peace, which some conveniently neglect or pretend wouldn’t matter if the situation were much different.

Europe relies on this exceptional spending and benefits from it, having a disproportionately strong power encourages peace.

Please explain how the US exploits Germany.

Pax Americana exists for a reason.

It's not just America though, any sufficiently imperialist nation can create a peace; Pax Romana, Pax Sinica, Pax Britannica, Pax Ottomana all exist.
