In recent days we saw a concerted effort to gather support for a military act of retaliation, due to use of chemical weapons by a regime (who isn't a member State of the CWC) against its own citizens. More than one country has voted against military reprisals due to the possible ramifications of getting involved in a complicated civil war.
Ask a humanitarian agency for options and you will get humanitarian probabilities. Ask a military force for a solution and they will give you a military solution. Truth is, killing to avenge killing in any situation has never accomplished anything but more dead bodies and fuel for a bigger fire.
In a proactive world perhaps peaceful, multinational action could have been taken long before atrocities were committed, before certain weapons were used and before military action is promoted to be the only viable action.
Then maybe, this would be more of a love story.
