I guess bulldozing and bombing public buildings tend to usurp the possibility of seeing any fruits of investment. There is no excuses being offered other than Israel is methodically stealing land and doing whatever it takes to try to completely break the spirits of the rightful inhabitants to persuade them to move. That includes brutal treatment. They are barbaric, plain and simple.
Lebanon was a beautiful city beginning when it was part of Syria until the French seperated it in 1926. It was the 1975-1990 Civil War that saw the country destroyed. And in large part it was due to Phalanges Libanaises elements and Israeli actions. But in spite of that, Lebanon was undergoing an economic boom and starting to reflourish when they were invaded and the country was again decimated in 2006 by ... none other than the barbarians from the south.
Bulldozing public buildings for punative terrorist action, you seem to be skipping that part. And yes, Israel has been stealing land too. Of course the Palestinians have given Israel every excuse to do just that. Everytime you blow up a kiosk or a school bus, the local government isn't going to feel bad about bulldozing the family home, or stealing their land. You seem to be skipping the brutality on one side while magnifying it on the other. And while Israelis aren't killing each other, I must say the Palestinians are doing far worse and killing more Palestinians than the Israelis are doing.
Regarding Lebanon:
You make a giant leap from 1926 to 1970's. It was peaceful coexistance for much of that time until Syria (which did not exist as a country since it was Ottomanterritory until the Ottoman fall in which the League of Nations decided to divide control between the UK and France, winners of WWI against the Ottoman's losing in WWI. In fact Syria did not even claim independence until 1941 (an empty claim until it was recognized in 1944). Lebanon was in a geographic area known as greater syria, not a political entity or country. It also was under Ottoman control until the Ottoman's lost WWI and then it became a French mandate. Lebanese independence actually came before Syria's as recognized in 1941 and held elections in 1943. Long before Syria ever established any kind of cohesive political unit.
It seems you are missing a number of points. One being that Lebanon was never a part of Syria, though many Syrians seem to think it was, or more to the fact, want to think it should be. A type of localized imperialism, not unlike Israel and some of their views of a "greater Israel".
Perhaps the largest act of instability was allowing Palestinian refugees to remain in Lebanon. Its seems that no matter where the Palestinian refugees go, they cause trouble. Look at their history in Jordan and Lebanon. The Phalange Lebanese played a very small role in that unstable history, especially relative to the Palestinian refugee situation.
In conclusion:
The Lebanese were independent with their own governing body before Syria was.
The Lebanese by and large desire to remain independent.
And it would seem that Syria doesn't like it and is willing to assassinate those that stand in their way. A reflection of the equivalent Israeli imperialism locally.
Regarding the barbarians from the south.
Why is it that Lebanon allows a rival army like Hezbollah to occupy its country?
Why isn't that independent army being blamed by you for dragging Lebanon into its personal war with Israel?
You seem to show a memory loss when it comes to the why's of things happenng rather than looking at the events as they actually are.
