Exactly. Can't do that in the era of #ResistDrumpf.
BTW, I actually learned about the stupid expanded Disney EU and this is actually explained, although it's still contrived as hell.
Basically, after the end of ROTJ, the galaxy split in two, with the Imperial Remnant and the New Republic splitting it up and both agreeing to disarm down to the bare minimum. Then a bunch of Imperial radicals buggered off to become the First Order and Leia organized muh Resistance to counter them, which the New Republic mostly refused to help because it would violate the peace treaty.
Of course the Imperial Remnant hasn't been mentioned at all in the movies because it was obviously made up afterwards to justify the galactic retardation of Disney Star Wars. #ResistSnoke is still a retarded name. They should've called themselves The Watchmen or something, because they aren't resisting, they're fighting for the status quo (just like REAL #Resist celebrities, maybe this is more based than we thought! ). It also doesn't explain where The First Order's near limitless resources come from, since despite actually being a fringe terrorist group according to muh deep lore, they keep building giant Death Stars and capital ships that keep getting destroyed because they're all retarded, just like everyone else with authority in Disney Star Wars.
