Syria: An Economic Solution

The problem of Syria lies outside of the country and therefore, a Syrian solution cannot settle the Syrian crisis. 
Today's Syria is the field of a proxy war, as Lebanon is arena of a proxy dispute with a lower degree than its neighbor, which made it difficult to resolve the Presidential crisis of this country. If the parties engaged in the Syrian crisis are just looking for a short-term victory, so continuation of militarism or attaching the useless option of diplomatic or political solution would be their only dead-end!
But it seems for some States, it has been recognized that continuation of war in Syria could only impose damage against the political credibility of engaged countries in the Syrian civil-war, and moreover that it is a threat to national security of many countries, it is heavy economic burden for State-sponsors of Syrian militants. 
Therefore, if the engaged States in the Syrian crisis come to an agreement to end the military and political battle in the country, Syria would enter a new stage. The post-war Syria would be like Vietnam after its second war, which was against United States. The author of Diplomacy book, Henry Kissinger can share his experience in this regard with the US and European governments. Since then, Syrian government needs friends that be able to launch big economic and reconstruction projects in the country. And it can be predicted that Syria would make new friends and find new enemies. 
There is no expectation that every State has an interest in planning for long-term but probably those countries, which have designed a long-term strategy for themselves would change the path of war in Syria.
