Syria has transferred long-range Scud missiles to the Lebanese Shiite militant group Hezbollah, Israeli and U.S. officials alleged, in a move that threatens to alter the Middle East's military balance and sets back a major diplomatic outreach effort to Damascus by the Obama administration.
First of all, there isn't a sane observer in the world who would argue against an "alteration of the Middle East's military balance," which routinely expresses itself in a casualty ratio of roughly 100:1 Arab to Israeli casualties. Getting that to a more even ratio, by enhancing the ability of one side to defend itself, is what I like to call a "sure-fire" recipe for peace! Otherwise, what history shows is that you can go on killing people for a long time before you'll ever see any benefit in negotiating with them!
Secondly, it's worth reviewing why there is a Lebanese Shiite militant group named Hezbollah in the first place. The short answer is that no such group appeared until the Israeli military appeared in Lebanon.
