Imcel was surrounded by 5 elders, an army of undead HKs, Admirals and lesser minions.
Of course no one wants smoke with all that.
It's crazy to think of how selfish the Celestial Dragons are compared to the Marines and most successful Pirate Groups.
Queen hates King's guts on multiple levels, and straight up told Sanji there was no way King would ever lose to Zoro, he was gassing the man up.
Zoro and Sanji fight all the time, and Zoro knocked Sanji out to take Kuma's Pain Bubble in Thriller Bark.
Even if Marines like Issho and Sakazuki have great disagreements, they can still have civil discussions most of the time.
The Gorosei treated Garling like shit until they realized he was one of them when he walked in, Imu toasted Saturn for an innocent mistake.
They all serve Imu out of fear, not true loyalty, and Imu misuses that power, when, think of what good it could do?
Like, it's clear some Gorosei are above most Admirals now, and it's likely some God's Knights like Shamrock are above them, too, in terms of overall fighting force.
Imu is so hyper-paranoid, that rather than use these forces to rule the world, Imu has to keep them next to them, out of fear.
I think Imu has to have some key/severe weaknesses, otherwise, Imu would deploy these forces more often.
