The reason why we shouldn't implore our governments to "do something" about an atrocity somewhere is that our governments are comprised of evil men (with a smattering of evil women - You've still got a long way to go baby!) who are either already complicit in this barbarism (witness Canadian "intelligence" agencies subcontracting torture to the Asaad regime in Syria) or they'll use your pleas as an excuse to get involved out of their own revolting self-interest and most likely make things worse.
