The war started when Arab Sunni Muslims were protesting against Bashar Al-Assad & it's dominant Arab Shi’ite Muslim government over basic human rights!! The Syrian regime decided to kill those protesters across the land!! Nations like the U.S., U.K., Turkey, Saudi Arabia and Qatar send money & weapons to the Syrian Rebels; Nations like Russia, Iran, Iraq, Lebanon and China did the same for the Syrian Regime!! If no country jump in, the war would've ended in 2 years!! Most likely, Al-Assad would win!! Because of the war, ISIS rose from the shadows & conquered territory in Syria!! The West failed cause they backed the Rebels who were too weak to beat the Regime!! Some of those Rebels joined ISIS or other Sunni Muslim terror groups!! Over 400,000 people are dead, 600,000 wounded, 10 million displaced, 6 million fled cause of the war!! I dislike both the Regime & the Rebels!! To end this war, the U.N. must send peacekeeping troops from all nations, establish No-Fly Zones, disarm the Regime and the Rebels, replace the Regime with an U.N. mandated government, return refugees back into Syria!!
