Blofeld’s and Spectre’s schemes in Casino Royale and Quantum of Solace were never intentionally directed at Bond, nor were they intended to be. Neither storywise nor by the filmmakers. Casino Royale was Le Chieffe’s mess and Spectre had to clean up. The fact that Bond became involved and was emotionally hurt was a nice byproduct for Blofeld. Had Bond not perused it further it could have ended there.
Bond bringing down Quantum and Green is what really got Bond on Blofeld’s radar in a big way. That’s why Blofeld gave Silva the go ahead to attack MI6 and kill M. Silva gets revenge and Blofeld disgraces MI6 which will lead to the end of the Double - O program and the creation of 9 Eyes.
“A nice pattern emerged. You destroyed my world and I destroyed yours.”
Blofeld’s schemes didn’t start at a direct assault on Bond but as 007 worked his way up Spectre’s ladder a direct confrontation was inevitable.
This organization that has plagued Bond’s career as 007 has a leader and a name and they’re one in the same. Blofeld IS Spectre.
“We have people everywhere.” - Mr. White, QoS
“He’s everywhere!” - Mr. White, Spectre
“Me, James. It was me. The author of all your pain.” - Blofeld, Spectre
