Let's lay down the facts guys,

The Maverick code says, "Reznov is dead. Or is he? there is no body is he says who he says he is." This means that Reznov survived the escape and is still alive. This code might appear sketchy but for how descriptive and complete with the story it is it is impossible to not be placed there unintentionally.

John Trent. Whether the wiki wants to acknowledge it or not Victor Reznov is John Trent. Through the CIA database John Trent quotes Reznov multiple times and has knowledge only he and Mason would have. This is aided by the end of the maverick code because he is not who he says he is.

Alright now onto Operation Charybdis:

According to the intel in the final mission of BO this operation takes place in 1978 and is a mission in which Jackson and a young SAS operative named Johnathon (Price in the French) go to South Africa to eliminate Mason, Weaver, and Hudson.

Weaver's sister is part of Jacksons team and her role is to seduce Mason.

The same year Mason learns Woods is in Hanoi, and also travels to Johannesburg (in South Africa). Now assuming that you take all of the obvious references to John Price as literal it looks as if he(as he would be young at the time) and Jackson are going after Mason in Black Ops 2. The thing to note is Jackson is still alive as of 1999 and John Price is also alive in January of 2017. So either Mason and his team are killed or they reach some sort of truce, which is unlikely.

There is Call of Duty Black Ops 2 as we know it. And in the matter of Kravchenko, as unlikely as it is that Woods survived the explosion(which he did) Kravchenko had the bomb strapped around his body. He doesn't have a personal connection with Makarov as Makarov is not as old as Price and even Price would be young at this time. Kravchenko being in MW3 is either as an influence on Makarov indirectly or as a throwback to Treyarch.
