back then countries were joining instead leaving

gpt
The only countries that joined since 2005 are Romania, Bulgaria, and Croatia. Not exactly a roaring ramp-up of high-profile membership. 
  
 And, today, exactly 1 country is possibly leaving, and probably wont, because turns out the EU is actually pretty good for them. If the EU doesn't exist by 2030, it'll be because it transformed into a larger or differently-structured union, not because it dissolves.
