What are akatsukis intentions i read it in the manga but i didnt quite get the three stages ?

Question

could somebody explain me

Answer 1

What the guy above said, however Pein's goal is to use all the tailed beasts to create a weapon of mass distruction which will wipe out one of the shinobi nations in an instant causing the rest of them to be detered from war ( or so he thinks) and madara the real leader wants to use the tailed beasts to return his eyes to there formar glory (so his sharingan are presumed damaged)

Answer 2

They plan on collecting large amounts of funding through various legal and illegal methods, and then set up a front of mercenaries to take on shinobi missions from all around for much less than the major hidden villages charge (using the previously collected money to cover things) and like this (since the other villages can't afford to charge so little since there haven't been any late ninja wars) they plan to take over all shinobi trade and ultimately end with world domination!
