Does intervention need to be in the form of military aggression?
Not necessarily
I am just wondering how the situation resolves without the UN having to get involved?
Not making a political point here
the latest is
"US Secretary of State John Kerry has said Syrian government forces killed 1,429 people in a chemical weapons attack near Damascus last week.
Mr Kerry said the dead included 426 children, and described the attack as an "inconceivable horror".
He did not mention military strikes, and said the government would consult Congress leaders over the next step.
The government of President Bashar al-Assad has denied carrying out the attack and blames rebel forces.
UN chemical weapons inspectors are investigating evidence for the chemical attacks and will present their evidence to the UN after they leave Damascus on Saturday. "
