Putin should stand up and say loud:

Poroshenko is killing civilians.

Porishenko is constantly lying about ceasefire. In reality he intensufies hesvy artillery attacks on civilians in Lugansk.

If OCSE and other internationsl organisations dont force Porishenko to stop shelling civil areas Russia will be girced to bring pecejeeping firce to Lugansk.

Loud and clesr. So far Putin us just mumblung something.
Even if Obama lies, he is mych more determined, proactive,sound...
