I merely stated the catalyst for the beginning of the uprising. It has now escalated due to the western world's reluctance to get involved, the complete antipathy of the gulf states and the involvement of radicalised nut jobs.
The "uprising" was caused by prolonged drought, the failure of farms, the movement of farmers to towns seeking work that wasn't there and the subsequent violent quelling of protests against the government at the time of the Arab Spring.
Amnesty International recently pointed out that the "six Gulf countries -- Qatar, United Arab Emirates, Saudi Arabia, Kuwait, Oman and Bahrain -- have offered zero resettlement places to Syrian refugees". This is DISGRACEFUL and needs focusing on as much as the situation in Europe.
