The document discusses the arguments for and against Britain intervening in the Syrian conflict. The arguments for intervention include removing the dictator Assad to bring democracy, preventing terrorist groups from gaining power in the chaos, and stopping further killing of Syrian civilians. However, the arguments against intervention are that it could lead to more violence and terrorist control, increase support from Russia and Iran for Assad, and risk war with Russia due to advanced missiles. In the past, British intervention in countries like Libya, Iraq and Afghanistan made things worse.
