Israel knows that it cannot underestimate its enemies as it did before the 1973 Yom Kippur War.
While Hizbollah is a potent force and controls all of Southern Lebanon, this article suggest that Hizbollah has been severely weakened, which it has but it has also gained years of combat experience against nut jobs nuttier than them. This means that they are battle hardened.
Now they have advanced Soviet (oops, I mean Russian) SAMs in Lebanon and Syria. This is a serious threat to Israel's control of the skies over Israel, Lebanon and Syria.
As long as the world gives Iran a free pass on her Nuclear program and lifts sanctions, Iran will increase her power 10 fold in the region with Soviet (oops, I mean Russian) help.
Hizbollah is down but not out int he same way the West thought the Soviet Union (oops, I mean Russia) was out in 1989.
Watch out and hit them whenever possible.
