My prediction for the situation on MH17 in 2020. I just hope I will be totally wrong.
JIT: between 2017 and 2020 JIT announced it was able to find the names of a few people involved in the logistics of transporting the BUK to and from Russia. As these people could not have been aware of the results of their acting JIT decided not to prosecute these people. There will be no court case against the people who had command over the BUK as the names could not be determined.
JIT was not able to find a motive for the shot down. Most likely because the motive is something which should not be made public. My guess Ukraine somehow provoked the launch of a missile.
JIT countries did not agree on an international court case or under Dutch or Ukraine law.
ICJ: the application filed by Ukraine against Russia was not accepted by ICJ as a case ICJ has jurisdiction on.
ECHR: a couple of next of kin filed an application against Ukraine for not closing the airspace. Case still under investigation.
Dutch government succeeded in keeping minutes of meeting of cabinet secret. The government did not take legal actions against Russia or Ukraine.
Dutch parliament. All members who were in opposition in 2014-2017 period are either out of parliament or member of government parties. Not much criticism.
Some member of Parliament talk about a Parliamentary inquiry on MH17 to find out what the government did in the years 2014-2017.
Dutch public has forgotten about MH17.
Dutch press. In 2017 (3 three later) and 2019 (5 years later) on tv a couple of documentaries will be shown with a lot of focus on the next of kin. No investigation into all aspects of MH17
