Now rethinking I have to change my opinion to = + and not = =. Ur post gave me points to rethink, though with some I dont agree.
Would the full might of the MHQ have any problem with Whitebeard on his own? No, they could hunt him down and kill him easily. But Whitebeard and 16 persons as strong as Ace plus another 1600 men who all survived to the New World? That's another job altogether.
So far only Jozu and Marco can be considered on Aces level. The other were not even given proper introdctuion by Oda so most likely they are not that strong. Also it is not only 1600 but alliance fleets as well as Garp already said (or hinted).
The second question you need to ask yourself is, why do the 7BK exist? The answer is that MHQ is not strong enough to defeat these pirates. They need extra help to be able to fight them. That alone rules out the equation MHQ=Yonkou in strength.
The MHQ should have enough power to fight the Yonko, but it is the great age of piracy. I will explain later.
The Yonko is not a united organisation, yet you are considering them as one:
- Fighting off four different, warring fleets is easier to do than fighting off all four of them combined as one super fleet. If the WG side (MHQ+mandatory call for 7BK) had the power to fight all the Yonkou, they would do it. They aren't doing it, which means they aren't strong enough. Since they don't have the power to do that, they especially don't have the power to fight the four fleets combined as one.
Why would they fight all four fleets as one? Its not like all Yonko are residing on the same island. The MHQ could move their forces silently (without any anouncement like with Aces execution on newspaper) to crush the Yonko one by one. They didnt do that cause they have to face other outlws as well, not only the Yonko.
The MHQ could have crushed the Yonko one by one, if it wasnt
the great age of piracy. The MHQ has to face every pirate (SN etc) and other outlaws. (Also it was said that the MHQ is the WGs greatest force so they might even have to fight Dragons organisation; but well lets put them aside. Since it should be the work of each countries royal force)
The reason whe they need the Shichi: The current age is the great pirate age since Roger. The pirates are dominating the world. The MHQ isnt capable on managing the pirates on their own.
Thats why they need the Shichi, not only because of the Yonko. The Yonko are only representing the pinnacle of the pirate age in the new world. (Also the reason why Garp put them together in one basket) But the MHQ has to spread their forces overall in the world, hence they are overburdened.
The Sichi are not only there to fight the Yonko, but also to oppress other pirates. Or why else should the WG let their Shichbukai reside in the first half of the grand line?!
They dont need the Shichi to fight the Yonko but they need them to fight the great age of pirates. Remember CPs goal was the ancient weapon. With that they wanted to fight the pirate age.
Yonko = Shichi + MHQ
The Yonko are representing the pirates. Thats probably why they are put in one basket even though they are not united. It is the great age of piracy, so they are the dominating power in the world.
The MHQ as the second powerfullest force is overburdend. The Sichi as the weakest are there to outbalance the other two. Since they are there to outbalance and since Mwk said they are equal to the marine I put them earlier ==.
And did you ever wonder why WB has spent 20 years being the "closest man to One Piece" and never actually took it? It's because if he tried to claim it, the 3 other fleets would gang up on him and kill him hard.
Well thats crap and u know that urself.
Just recently we were told by Sengoku WBs intention. We dont know anything abouit Raftet and why Roger was so far the only man on that island. Nor dont we know anything about the goals of the other three Yonko..
WB was Rogers equal and rival; why would he want to step into his footsteps as the next PK? Though not called PK, he is allready the King of seas, according to Garp. I dont get how u came up with the gang up thing.
edit
So now you should be asking: Franckie, I don't understaaaand-tebayo, what the hell does all of this mean?
So you are looking down on me?
