You must be new to Malaysia. This is par for the course for their government. They really are that useless.
The Malaysian government really is just that bad. It's what happens when a government stays in power for around 55 years straight.
Not saying I don't disagree in certain respects, but having followed this whole thing really, really closely I believe the people who were in charge of this (for better or worse) handled this as well as they were able to barring the first few hours after it disappeared off secondary radar.
Getting immediate help from AAIB/NTSB/etc. pretty much was the right thing to do, and you can not hurry up a schedule that simply can't be hurried. Barring one or two obvious screw-ups in terms of information flow (the sequence of ACARS/transponder shutoff for example) making sure to only release verified information was the most responsible course of action.
The main fault here lies in that:
1) The alarm was not raised immediately/sufficiently and/or propagated to all relevant parties after the plane disappeared from secondary radar.
2) Stemming from 1, an unidentified plot on primary radar flew through sovereign Malaysian airspace without any real-time response. (The official answer/excuse is 'it was non-hostile')
Those two alone pretty much let the whole situation spiral out of control, leading to the huge amount of expended resources/etc leading up to the situation we have today.
Would there have been a different outcome had military aircraft tailed the plane in real time, all the way to its final destination?
Would the opposition government have handled this any better had they won the elections last year? (Which I assume is very, very relevant as a subtext to the two quoted posts)
Those two questions are difficult to answer, and my personal opinion would be a "yes" to the former and "I don't know" to the latter.
