Just read this.....
Israel reportedly planned recently to bomb one of the arms convoys as it crossed the border into Lebanon, but the operation was called off at the last minute. Western intelligence sources say that the Israelis have yielded — for now — to American diplomatic efforts to persuade Syria to stop the arms transfers. However, the apparent lack of success is increasing the chances that Israel may send a “calibrated signal” to Hezbollah and Syria by launching an airstrike against an arms depot or weapons convoy
Sounds like a way to get things hot.
