Garp = Rogerthe whole western world was after Bin Laden :/
also no matter how strong you are you can still sustain heavy casualties (more than you can afford to) fighting against someone weaker than you, OP example: Marineford, IRL example: Vietnam War, an outright war with someone as strong as a yonko (and his/her crew) isn't a simple thing
so waht if only Garp and Whitebeard are mentioned? does that mean he walks over everyone else? everyone who read MF knows how Newgate did against Akainu and the other 2 admirals aren't far behind (if at all) same for Sengoku, he was teh FA so he's teh second marine who should have been to compete with Roger and Newgate
Sengoku = WB
WB /= Roger
Despite being close, Roger would have edged out WB given everything we know so far about the two. Also these are primes, Akainu >80 year old sick WB ok that's not saying a whole lot, because even though he was still so much stronger he wasn't in his prime just like Luffy wasn't in his prime at MF so to say Akainu > Luffy when they didn't fight at their peaks isn't a solid argument.

^ This isn't relevant let alone accurate. Germany wasn't looking for him, France wasn't looking for him, Guam, Peru, Argentina etc. etc. hell the American government wasn't even looking for him until his family's buddy Bush got out of office.
