THE PBS News Hour report with Margaret Warner above will give you the best idea of what happened.
There has been analysis, including some quoted at the Council of Foreign Relations, that Assad falling would make things more difficult for Israel.
There are also experts who disagree with this assessment. Their assessment comes down on the side that there is an equal chance that when Assad falls Iran will lose its main ally against Israel and lose power in the region. This is what I believe is even more likely than Assad’s fall hurting Israel.
That’s not where we are today. Instead, we’re at a very dangerous moment yet again, though the Israeli strike was something the Netanyahu government obviously believed was necessary.
The American officials, who spoke on the condition of anonymity, said Israel had notified the United States about the attack, which the Syrian government condemned as an act of “arrogance and aggression.” Israel’s move demonstrated its determination to ensure that Hezbollah – its arch foe in the north – is unable to take advantage of the chaos in Syria to bolster its arsenal significantly.
The predawn strike was the first time in more than five years that Israel’s air force had attacked a target in Syria. While there was no expectation that the beleaguered Assad government had an interest in retaliating, the strike raised concerns that the Syrian civil war had continued to spread beyond its border.
