I have not done a study of it as every time I begin I get otherwise occupied. I do think quite possible Jesus comes in the clouds before any of these actually take place...but even then not sure we won't see some of it.
Syria's behind a rock and hard place right now...so interesting to see how that's going to play out.
Have you read Isralestine by Bill Salus? You can get it dirt cheap from eBay and it is extremely interesting.
