Enemies become friends, friends become enemies. Geopolitics works that way. Always has.

You can have my Monday Morning Quarterbacking when you pry it from my cold, dead hand.

Barbarians or no, the problem at the time with helping the muja wasn't that it would blow up in our face in 20 years. No one even considered that, beyond your Monday Morning Quarterbacking that "no great power ever suffered disaster by relying upon barbarians to fight their battles for them". In the grand scheme, most major powers did fine letting barbarians do the fighting. In the Empire days it was pretty much standard operating procedure. A lot of the problem is pretending that barbarians are human and don't need a firm ruling hand to keep them in line.
