Personally I prefer the idea that they’re only sending a couple ships, if doing anything at all. I should write something more in-depth on this, but the way I see it, one of the primary themes in the sequel duology (I mostly disregard TROS when possible) is the cyclical nature of things: interpersonal, societal and mythic. The Force Awakens is about cycles repeating and The Last Jedi is about finally breaking those cycles. I think for that to land, it’s important that the New Republic becomes complacent and mired by beauracracy the same way the old one did. As old GL one said “It’s like poetry. They rhyme.”
