reasons of syrian war to start~
1- Gas pipeline from Qatar/Saudi arabia connected to Europe, Russia didn't like the idea because its the only gas provider to Eu countries.
2- Syrian people were only two classes , VERY rich or VERY poor nothing in the middle.. people wanted better jobs better incomes, Al Assad family took the power by force for 40years.
3- Syria has nature gas and oil that still underground and fresh waters, there's also gold aswell
