Horrific things have not just been happening in Syria for 4 or 5 years; they have been happening since the Assads and their cronies took control of the country:

I think it was Robert Fisk in his book Pity the Nation who described visiting the site of the Hama massacre and meeting an old man wandering about in the rubble. When he asks: “What happened to the people who used to live here?” the old man replies: “You are walking on them”.
Having visited Syria about a dozen times I have fond memories of the place and the people and wish I could do something to help. I can only console myself by hoping that once people have left the country their lives will eventually improve, when the wounds have healed. My agent in Jordan is Chairman of the chamber of commerce in Amman and he tells me that this year around 700 new businesses have been established every month in Jordan by Iraqi and Syrian refugees. Consequently the Jordanian economy is booming and one can only hope this will benefit the refugees in the long term.
My brother lives in Michigan amongst a large community of expat Lebanese and I’m sure that those people enjoy a far higher standard of living as well as greater security than the ones who still live in Lebanon.
