It is true that the US is responsible for the "freedom fighter" terrorists that have thrived in Syria as we supplied them with weapons and encouraged them to wreak destruction throughout the land in the name of democracy.  Nevertheless, the best we can do for the Syrians is to leave the country alone and let the government with their responsible Russian allies restore order and allow peaceful people to get on with their lives.  So yes, write to congressional representatives, but tell them to leave Syria alone or better yet join with the Russians to restore order there.  Many more lives will be improved than by continuing to sow discord and then taking in those displaced.
