I believe the point he was making was that those alliances were never 'true allies' of the NPO and thus in the end contributed to their downfall. Looking at it in a cost/benefit kind of way, NPO gained very little in the end from having you as allies (no offence but they never really needed you untill this war and well, look how that turned out). At the same time it could also be argued that having you guys as allies lulled NPO into a false sense of security, which is fair enough seeing as Sparta for example dropped their MDoAP with NPO just to attack ~2 days later, which is quite the reversal in relations. Another point worth looking at is you guys were a major driving force; if not the major driving force behind the BLEU war; which split the Orders and arguably lost the NPO a huge amount of potential strength (through NpO and their allies). I remember one of the arguments BLEU members were making towards NPO in the BLEU war were "who will fight for you when Citadel betrays you?". Whether you want to call it a betrayal or not, the sentiment behind the idea is the same.
I think that's what Mussolandia meant but he can feel free to correct me If I misinterpreted
