Well think of how they split up the tailed beasts among the Great shinobi nations:
Sunagakure: 1-tail
Konohagakure: 9-tails
Kumogakure: 8-tails, 2-tails
Iwagakure: 4-tails, 5 tails
Kirigakure: 6-tails, 3-tails
Takigakure: 7-tails
Suna, a country that most of the people deem to be the weakest in terms of military strength, has only the 1-tail, who, by possessing the least amount of tails of all, is presumably the weakest of all the tailed beasts in contrast to other countries like Kumo who are considered to possess the greatest of military strength holds both the 8 and 2 tails in its custody.
Even Taki, a village not as well known as the other 5 nations is in possession of the 7 tails.
It makes one think as to why the tailed beasts were split up in this manner to balance out the power in the other countries...
