lol, only in your sci-fi wet dreams...
Has it ever occurred to you that maybe that building was a little more stronger than the surrounding buildings and that the trees being skinny offered little surface area to be pushed down and they are flexible?
Has it occurred to you that nukes are more likely just a scare mongering tactic that cannot do anything destructive unless they're used in fictional books or TV films?
Do you have any proof?
That's down to interpretation and using detective skills and common sense, plus hunches. You know, that kind of stuff.
Is it a proof?....No it's not, but as iWitness said: nukes
can't destroy concrete buildings but jet fuel can......

If you have no issue with anything and don't feel like it deserves further digging, then leave it and accept it. The thing is, plenty of people do have an issue and they aren't all flat Earth theorists, either.
This nuke stuff has a strong smell of bullshit about it in some aspects. Proving that would be nigh on impossible for the average Joe, or even the above average Joe.
Even in the 40's when the bombs were allegedly detonated, the news channel had it down as a propaganda machine in motion, citing that there was no nukes.
