MH370 & MH17: Has Malaysia Prime Minister Najib Razak became a puppet for TBTP and MAS airline is now a murder tool?

For those who still remember this, 7-8 years ago, the current prime minister of Malaysia Najib Razak(back then the minister of defense) was involved in the Scorpene Submarine Scandal. This was brought to the public attention after the murder of a Mangolia woman named Altantuya Shaariibuu. She was a translator for Najib back then during the Scorpene Submarine deal and was said to be murdered because she knew to much about the scandal.

Two years ago, the French started investigating this case but no further news was heard after that. So what happened to the case? How did Najib got away with such a big crime?

I believe he made a deal with TPTB. As long as he follows their instruction he will be safe and no one will dare to catch him.

Were the MAS airplane MH370 and MH17 two of those "instructions"? And will there be more?
