War and loss of life is always terrible, but the civilians in Syria are not being given anywhere safe to live. Innocent children are being killed, the infrastructure of the city is being bombarded by artillery and air strikes, leaving no resources to help those affected and injured within the war zone. The Syrian refugee crisis is an issue we will likely not resolve soon, and the Syrian civilians, innocent bystanders, are being caught in the crossfire. The Syrian leader has a right to fight for his country, but he is also responsible for protecting his people, which he has failed to do.
Syrian President Bashar al-Assad deserves to be tried for war crimes. He has actively sought to destroy his own people in order to maintain power. He's also used illegal weapons against his people. With no end in sight, it's difficult to imagine just how many more lives will be lost and ruined. He must be held accountable.
Yes, the Syrian leaders should be tried for war crimes because children have nothing to do with a war. They are not fighting for one side or the other. To murder a child during war is to take an innocent life. Therefore, anyone who kills a child cannot use the excuse of war.
This is a pretty horrific example of a war crime. Most civilized nations aggree that to kill civilians, particularly kids is a war crime. To kill so many is unthinkable. As soon as they can find the Syrian leader or leaders who are responsible for these actions they should be put on trial.
War crimes are about whatever "justice" you can afford. Saddam Hussein used mustard gas on his own people and the Iranians which is an undeniable war crime, but the only reason the US went after him was because he invade Kuwait which is a country we invented just to pump the oil out from under him. Others like Idi Amin Dada were flat out insane feeding thousands to the crocodiles and cutting off his own mothers arms and legs and having them sown on backwards, but so long as the money and guns rule the world there will never be any justice in or out of court, least of all, in the US.
