Yes, now it is evident that Russians have planned this action just to accuse Ukrainian army. To some rulers people of other nations are just collateral damage on their way to gain more power. They will try everything and anything to hide they real intentions, but the truth always emerges.
These include a "natural human delight" in complicating matters and telling a good story; proving that an enemy is "not only bad but demonically cunning"; making money; and that a proportion of them are true. For all the ludicrous theories that exist, there are also some real conspiracies out there.
Although the missile that shot down flight MH17 was from Russia, it still could have been fired by people with nothing to do with Russia. No one has accepted responsibility for this action. Those who hold various conspiracy theories are unlikely to change their views simply because the missile came from Russia.
Conspiracy rumors will continue to spiral until solid evidence is brought forth in the matter. Russian representatives continue to deny Russia's involvement and cite the apparent lack of detail and proof of the missile launch site to support their denial. Until undeniable evidence is brought to light, conspiracy rumors will continue to circulate.
