Just like we (the US) should have consulted the Taliban before we went into Afghanistan after Osama.....?
Syria is a KNOWN terrorist state that is one of the biggest supporters of Hamas and the palestinian terrorists, as well as terrorists around the WORLD.
As far as I am concerned, if Israel wanted to blow Syria off the face of the earth, they would have many legitimate reasons to do so. The fact that their strike killed zero tells me that they in fact did use restraint.
I also haven't heard Syria deny that the Israeli target was a Hamas training center. They are only focusing on the "unjust" violation of Syria's sovereignty.
