>intel is just bullshit just to implant those measures
If you are going to assume without evidence and offhand that everything the American government says is bullshit, you might as well go ahead and join the terrorists because you seem to believe that we support and work for an evil, manipulative and deceptive regime.
I am going to believe what the US government says about the raids until there is evidence to the contrary. I believe things on evidence and not because I hate or have an ax to grind with certain countries.
>Or do you think that terrorists are naive and won't use other airlines and origin airports?
Maybe they are just applying greater precautions to areas deemed high risk for attacks, like they have always done - did you consider that. I am not angry because the precautions cannot perfectly protect us from attack, because that would be as unreasonable and irrational as being angry that they are taking any precautions
Step 2: OK, it doesn't look that risky. Still, you never know.
Step 3: I know, that new security check/ban/whatever has non-trivial costs. But we can't do nothing, can we?

It's a matter of assigning blame. If whoever calls the shots change nothing, and something happens, his head will fall for ignoring that new threat (even if he didn't and made an actual cost/benefit analysis).
Similarly, taking someone off a watch list is very hard. Also see how we are sliding towards a total surveillance state, ostensibly to stop terrorism and child abuse, but actually to stop particular forms of copyright infringement.

Or perhaps that intel is just bullshit just to implant those measures
