Southern Lebanon was illegally occupied for 18 years. Israel still holds Ghajar bordering Golan and Sheba Farms. It's valued for its water resources.
In 1981, Israel destroyed Iraq's Osirak reactor. Baghdad didn't retaliate. In 2007, an alleged Syrian nuclear site was bombed. At the time, evidence of one was suspect. Later confirmation proved none existed.
IAEA head Mohamed ElBaradei said its experts analyzed satellite imagery. They concluded that the building struck was not a nuclear facility.
In February 2008, Seymour Hersh headlined "A Strike in the Dark," asking:
"What did Israel bomb in Syria?" On September 6, 2007, four Israeli aircraft entered Syrian airspace. Secret unprovoked bombing followed.
At the time, tensions were high. "(B)y almost any definition," Israel committed "an act of war." It said little. Syria denounced what happened.
A military spokesman said Israeli planes dropped munitions in an unpopulated area. Syrian air defenses "forced them to flee."
Weeks later, Assad said Israel warplanes struck an "unused military building." He added that Syria reserved the right to retaliate.
