I believe there will never be a courtcase on MH17. All states involved rather keep the truth hidden, for their own reasons.
There could be three suspects:
- Russia delivered a single BUK TELAR and operated it
- The separatists captured an Ukraine Army BUK TELAR and operated it
- Ukraine executed a false flag scenario with a BUK
- A different scenario which we can only speculated about.
If the Joint Investigation Team believes Russia delivered the BUK, which is I believe their many theory, Russia will never cooperate with the court case. I do not think a courtcase will be done without a suspect in sitting in a court building.
Ukraine is part of the Joint Investigation Team. Ukraine will not cooperate with their own conviction. Ukraine is too important in a geopolitical way. The United States will defend Ukraine like it did to France in the Ustica shot down.
Ukraine simply cannot be the suspect in the current relations between US/EU and Ukraine.
So how to find out truth?
First the official investigation will need to be finished. Then it needs to be decided if a court case will be started.
If there will not be court case in a couple of years, a Dutch parliamentary investigation will likely start. If the outcome will show that there are a lot of unknown facts, a second investigation by a Dutch prosecutor will start. My guess is that will not before 2021/2022 or so. At that time the current Dutch government has been replaced, maybe relations in EU have been changed.
In my personal believe MH17 will follow the same path as the Itavia DC9. After about 30+ years the truth came out but still not for 100% certain.
