The challenge is,with a POD no earlier than 1815,to prevent the USA from becoming not only a superpower,but also a first rate Great Power,meaning for example in a early 20.century OTL context it is considered at most an equal to italy or austria-hungary,but not britain or germany. Both economic and military might are to be put in consideration.
Additional rules:
1: The United States must still exist as a nation by today,though it does not need to cover all OTL lands.
2: Achieving Superpower/first rate great power status but then loosing it in any way does not count.
Bonus points if they are never even considered a Great Power at all,staying at Brazil or Argentinia levels.
