Jim, are you being naive or disingenuous?
"Deep concern" is just about as mild a rebuke as you can get!
Imagine the outrage and breaking of relations had US pulled such a stunt in any other country on earth!
Even the closest of allies such as Britain or Israel.

Al Qaeda and the Pakistan government are sworn enemies.
Thousands of Pakistanis have been killed and they are greatful for anything US does against them.
It is just that their security and intelligence services are heavily infiltrated, and America is not popular.

They express concern over the predator strikes too, but never demand that they stop.
