The war in Syria

With the United States getting involved more with IS, what happens? My prediction:the United States does most of the damage to Assad rather than IS causing his government to lose the war. Our puppets become the new government, ruining yet another country.
 
Syria isn't ruined already? The civil war has damaged a lot of infrastructure and the economy, and it's gone on long enough to draw in foreign religious zealots.
 
Russia, Iran and Turkey have signed a deal calling for the setup of so-called de-escalation zones in war-torn Syria during talks in Kazakhstan's capital, Astana.

The signing ceremony on Thursday was briefly interrupted as some members of the Syrian armed opposition's delegation stormed out in protest against Iran's participation in the deal.
