Airline security in China

Every time I fly I wonder - do these security measures they are imposing throughout the world really help to catch terrorists?

Take for instance that humiliating search we have to go through every time. They will make you take off your shoes, unbuckle your belt, will look into your wallet and count all the money there... and now they even will check your laptop! And don't even try to bring any liquid with you, even if it's sealed 50 ml bottle of allergy medicine - you'll have to open it and they won't give a damn that it must be stored in the fridge immediately after being opened or be thrown away after three hours. There are no body cavity searches yet... but looks like these will be mandatory soon. And don't get me even started on that stupid ban on lighters and matches!..

On the plane they'll make you turn off your phone (flight mode is not enough now - apparently you phone's LCD can interfere with avionics) and sometimes will tell you to turn off your MP3 player as well. The reason for this is unknown - they just make you do it...

What's hilarious in all this is the fact that exactly zero terrorists were caught thanks for these measures. For me it loks rather like psychological study: How much humiliation will people swallow before they are fed up?
