The Ukrainian Parliament acted wisely giving consent to send 950 armed soldiers and investigators from Australia and the Netherlands at the Malaysian airliner crash site. Thus, the idea proposed by Russian Foreign Minister Lavrov to send "Russian peacekeepers" to secure the crash site has lost grounds.
The insurgents are in a difficult position. If they do not agree or try to sabotage the mission, it will become clear eventually that they are not interested in clarifying the circumstances.
The Dutch and Australians were not involved yet in the conflict and the pro-Russian militants and their patrons in Moscow are forced to recognize the primary interest of both countries in the investigation because of the large number of their deceased citizens. But it will become a very difficult task even for the Russian propaganda machine to explain the purpose of a backup group of foreign soldiers in Ukraine. It is good that the bodies of all the dead may be taken away even if many clues have been destroyed.
