The death toll in Syria has now risen to over 470,000 casualties according to the Syrian Center for Policy Research (SCRP). With the recent intervention by Russia in an effort to prop up the Assad regime, the death toll has continued to rise. The Assad regime and its Russian allies regularly engage in indiscriminate killing in the form of sarin gas, barrel bombing, and executions. The rebellion that began in March of 2011 has since collapsed.

Aleppo has now fallen, and the situation in Syria has become increasingly complex. It's a civil war between the people of Syria and those loyal to Assad's dictatorship, it's a proxy war between the United States, and Russia and Iran, and it's an opportunity that ISIS has taken to wage war with its own twisted ideology. With such a complex conflict, a lot of the information surrounding it can become extremely confusing. So, let's break it down.
