That is not at all 'evident' which is the point of this increasingly odd thread. The article does not make such a claim.
Many of us know what terrorists born in the 1950's did, but somehow we all miss the fact that they all belong to the same generation. Weird, eh?
A lot of people think they know who Vladimir Putin (1952) is, but how many of them are aware that twenty years ago Putin was involved in the Chechnya war?
The article doesn't make such a claim, but it also doesn't make a contrary, leaving it to the structure, which feels questionable.
