the notion that the entire world government fought whitebeard is crap, Balckbeard had tons of non-blackbeard pirate allies and of the five shichibukai that came, none of them really did much, the most was taking down oars (isnt apart of the blackbeeard pirates) and they didnt even break a sweat. However this thread is still debatable as it is already known that any yonko captain>any admiral (after sengoku and garp retired that is). but mihawk was known to be around shanks level and doflamingo is about equal to or stronger than an admiral.
as i see it the seven shichibukai could match up to Big mom and Kaido with doflamingo and mihawk
and the admirals/vice admirals combined could fight the other two. I dont think any yonko could beat both akainu and kizaru at once (i doubt whitebeard could have)
the final trump card in the world governments favour....well two of them
1. CiC Kong, he was once the fleet admiral so he is/was a combatant, and to be fleet admiral above sengoku says something.
2. CP0, the elite haki unit used by the WG to capture Byrne World
and finally some of you confuse WG to be just Navy+shichibukai+CP
they do have a world military too (where issho and the other new admiral came from)
the yonko are stronger than b4 with BB instead of WB but while issho and the other admiral were in the military anyway, the WG has gotten weaker overall losing sengoku and garp,, i still see the WG winning.
But even then, Blackbeard was shown after time skip to actually be running from navy
in conclusion the WG is larger than alot of the people here think. Combined, they would wipe thier asses with the yonko, but its too risky to ignore all the other pirates and Dragon, maybe thats why they havent done so
