Ask HN: How to hack wars?

The Russian government denies the use of chemical weapons by the Syrian regime, while accusing White Helmets of faking such attacks that would allow US, France and UK to open fire in Syria. The US, France and UK pretend such attacks already happened in Syria in the past. As citizens, how can we figure out the truth? As citizen, should we be responsible for letting governments do remote military operations without a way to know what actually happen on the battle front?
