Here is a good letter to address your Congressman with!

I urge you to not support United States military action in Syria. Action in Syria would further anger the close allies of Syria such as Iran and Russia against the United States of America and could lead to a broader scale of war. We cannot afford to send out our tax-dollars or military assets to intervene in Syria's Civil War. The alleged chemical attacks in Syria by the Assad regime is terrible, but it is not the United State's duty to be the world police, especially with the economic state that our country is presently in. The proper channels to deal with this alleged chemical weapons conflict would either be the UN, who has proposed a diplomatic stance and the Arab League, who has stayed out of it so far.

Syria is not the United States' business, so once again I urge you to vote no on military intervention in Syria!
