I know this is not the forum where this goes but:
How or why would an airport say in Pakistan improve security when the TSA have no jurisdiction?
I believe the responsibility is on the airline to show that they have read, understood and implemented recommended actions to address the TSA concerns.
So if the airline flies to the US from Pakistan they probably will comply with these temporary measures.
Of course I'm curious what impact it will have on me as a passenger, but some of this stuff is behind the scenes.
