Why the world is silent against the crimes committed by Russia and Iran in Syria?

 What's in it for Russia's bombing of innocent people? Are these crimes at the request of Iran's mullahs?Do the mullahs to stay in power resorted to Russia?
These unanswered questions for the people of the world.

Moscow, AFP, August 19, 2016 - Russia said on Thursday it was ready to halt fire for 48-hour periods in Aleppo from next week, following UN calls to extend humanitarian pauses to deliver aid.
'Russia's defense ministry is ready to support the proposal by UN envoy to Syria Staffan de Mistura regarding the introduction of weekly 48-hour 'humanitarian pauses' (in Aleppo),' defense ministry spokesman Igor Konashenkov said in a statement.

'We are ready to implement the first 48-hour 'humanitarian pause' to deliver humanitarian aid to Aleppo residents as a 'pilot project' already next week in order to ensure safe cargo deliveries to the city's civilians.'
'Specific dates and times will be determined after information regarding the readiness of humanitarian convoys is received from the UN, as well as confirmation of safety guarantees from American partners,' he said.

Russia last week declared it would hold three-hour pause in artillery fire and airstrikes daily around the ravaged Syrian city but the UN decried this as insufficient to help the approximately 1.5 million people in Aleppo.
