Yeah, I don't buy that. It's bit soapy, everybody being interrelated.
If it were coincidence, then yes. But if Bond's career had been 'helped' along by SPECTRE, then no, it's not coincidence, it's planning.
RE everyone's point that Bond should've recognised White if he were indeed Hans Oberhauser: I've already suggested brain washing/conditioning as a plausible rationale to this. If SPECTRE had indeed instigated and arranged young Bond's placement with one of their own assets, then it certainly wouldn't be so that they could make him a happy wee chappy and pat him on the back at the end of his happy fostering with some fond childhood memories... It'd be so they could condition and prime the child to be their future asset, which obviously entails brain washing and memory manipulation.
This could involve initiating and keeping the child into adulthood, to take up the 'family business', but this would require the child being theirs from an earlier age than 12 (which Bond was at the time). This 'family business' profile could fit Blofeld.
With a 12 year old Bond, already in an emotionally fragile state after his parents deaths SPECTRE could very plausibly condition, brain-wash the boy, planting seed and directives that are buried in the sub-conscious, memories of this brain washing replaced with cliche, happy images of skiing and first female encounters.
The sinister directives now wait to be woken by the correct prompt. This prompt could be musical - it could be the 007 theme tapped out on the rim of a champagne glass as perhaps Waltz did at the end of the teaser trailer. This sets up a thrilling story in which Bond takes Blofeld's orders and the audience are left to dangle in the hurricane wondering when/how/if Bond's conditioning will be broken.
In this scenario it's entirely plausible that Bond's memory of Oberherhauser had been manipulated and supplanted with another. Perhaps that's a fake photo - part of the conditioning given to teenage Bond when he returned to England. It would be a nice moment for White to prove this unbelievable story to Bond (who's in denial) by showing Bond the original photo in which White is the figure in the middle.
Even if it's not White in the photo, the rest of my plot idea would still work very well. After all Bond's brain washing was a story line used by Fleming himself.
ETA: Just seen the comment about White having been interested to meet Bond. That's a very good point indeed. I'm sure Logan could post rationalise this if he wanted to - White hadn't met Bond face to face since that brief fostering. However, as an alternative (which i've suggested on a previous page of this thread) White could've been the 'foster-fixer', as i'd already just said, he could've placed young Bond with the sinister Oberhauser family on behalf of SPECTRE - i can see the creepy Mr White as a Fleming-esque Kiddy-Catcher.
I think it's pretty obvious this story revolves around that fostering period and that's too random for my liking if SPECTRE didn't play a part in it. Blofeld has to be the other child in the photo - the torn image of the other child obviously signals the film's big question: Which of the character's we'll meet in this film will ultimately reveal themselves to be that child - who is Blofeld?
That suggests there could be a twist at the end and instead of Waltz it's Scott, or even Bellucci (the other child in the photo could be a girl). Or they could pull a total shocker and have an unannounced star reveal, such as Mendes collaborator Spacey (i doubt and hope that doesn't happen)
I do like the idea of Bond's mission being helped along by Scott's seemingly sympathetic character, only to find out that Scott was having Bond do his dirty work for him; removing Waltz from the head of the table so that Scott could fill SPECTRE's power vacuum as the rightful heir. This would create a great springboard from which to dive into the next movie, as Bond hunts Scott's Blofeld.
ETA2: Yep, just watched the teaser again and i'm definitely going with Sleeper Agents theory... I think that meeting includes members of MI6 and Waltz is confidently welcoming someone he assumes is under his influence having been successfully activated and has come 'home'.
I'm really hoping that tapped out Bond theme we hear is his 'Manchurian Cndidate' activation method - played on a glass, or perhaps the chimes of a clock? It's a damn clever way of making the theme - an intangible part of the Bond meta-verse - a tangible part of his reality; just like they did by having CR's pre-titles toilet fight end with Bond doing the iconic gun barrel turn, shooting the man aiming his gun barrel at Bond.
The central theme throughout this reboot has been that of the original novel - identity crises. Brain washing Bond in his childhood takes identity crises to the Nth degree and that in itself, as much as the clues in the teaser lead me believe that it's Logan & Mendes obvious conclusion to Craig's incarnation.
