It's not that they thought these people would be their staunch allies, it's just that they had no other choice.
If Kael hadn't first revealed his absolute trump card—the technology related to building the Floating City—Yibel Federation's current predicament would have been even more difficult.
However, there is no "if" in reality.
In fact, even if Kael hadn't played the Floating City card as the main product for the Yibel Federation's interests exchange, the various great countries and powerful forces would still choose to support Yibel Federation.
The reason is simple: a dead Yibel Federation might not be beneficial to them.
If the Yibel Federation, standing at the forefront, falls, then they would be at risk without any barrier against Holy Briania.
As it stands, the only one that can contend with Holy Briania on its own is the Yibel Federation, so as long as they want to retain enough autonomy, they must hide behind Yibel Federation and support it.
