A single one on paper but a heavily divided one in practice where every country wants to be king or at least backstab everyone else to get what it wants.
I sometimes wish we could abolish our nations and replace the current treaties with a voluntary merge of all participating countries, making everyone simply citizens, throwing out all national law books and replacing it with a single Continental one.
Won't happen without a war - so hopefully not within my lifetime, but playing make believe is fun sometimes.
How would a war in Europe unite people under one leadership? See the regions that have been ceded and annexed post WW1 and post WW2, they still have beef with the new host countries bickering about regional autonomy. You can conquer land, but conquering people is a lot more difficult.
