I would have to agree.
I can't buy that Bush ordered Merkel's personal phone tapped. Would he have wanted intelligence about the German government's direction and policies? Hell, yes. But that can be done without tapping the leader's personal phone.
On the other hand, I believe every one of these taps was ordered by Obama. And they were not ordered in the interest of national security. Instead, I believe the driving forces behind the order were a.) his curiosity, b.) the possibility of gaining a political edge for himself and c.) "I won...and I can do it."
Megalomania, the relentless compulsion to accumulate, facilitate power and control, where absolute power corrupting absolutely, is the primary characteristic of the Sociopath's persona.
