However, in the actual context of that paragraph, I don't think they play that much a role in allowing "Europeans to stop other Europeans getting above themselves". (So I agree that there's nothing in that paragraph that's not roughly correct, but there is an implication that these are main factors.)

To give another direction to this sub-discussion; I'm only at pdf page 17 now so don't know if it is covered later, but, IMO, there is a logical sequence of these European attitudes:

1. there are real conflicts of foreign policy interests between EU member states,
   
2. earlier bouts of American divide-and-rule [a policy named by the report explicitely on page 12 as one of four] exploited these,
   
3. EU member states act as vassals and client states and hope for special relationships rather than act jointly ( = EU foreign policy paralysis).
