From The JPost, 6 Feb 2010, by HERB KEINON:
[Foreign Minister Avigdor Lieberman] ...said ... “It needs to be understood that we are not looking for either confrontation or friction with Syria, but when the Syrian foreign minister says that they will attack population centers in Israel, that is crossing a red line.”
[Earlier] ...Wednesday, Syria’s Foreign Minister Walid Muallem warned that Israel “should not test Syria’s determination” and added that Israel “should know that a war will move to Israeli cities.” Lieberman said that Assad, the same day, delivered a similar message.
“A red line was crossed like we have never seen before,” Lieberman said. “A direct threat to attack population centers."
...Lieberman said he was opposed to a withdrawal from the Golan Heights. “I think that the Golan Heights need to remain a part of Israel,” he said. “Just as Syria gave up on its dream of Greater Syria and opened an embassy in Lebanon, there is no reason why that can’t happen in our case as well.”
...Reacting to Lieberman’s comments on Thursday, [Syria’s official newspaper Tishreen said in an editorial on Saturday] wrote, “The path to destruction could lead to the moment that Israel will comply with its leaders, who have criminality flowing through their veins... Whichever path Israel chooses, it will find Syria ready for either peace or war.”
