Many questions about the acting of the Dutch goverment on MH17 remain unanswered in 2014,2015 and 2016. The Dutch goverment has the opinion not to interfere with prosecutor and Dutch Safety Board.
However the behaviour of the goverment is not as it should be. An overview of weird behaviour is here.
In my personal opinion a so called parlementaire enquete is inevitable.
So when will it be held?
As the prosecution will take some years, and the parlementaire enquete cannot be done while the prosecution is still not finished, it will take over 5 years before an enquete can start. It think it will be closer to 10 years.
The enquete into the Bijlmerramp started 6,5 years after the crash of the ELAL aircraft.
