Now before you laugh and head off to get a coffee, just stop and think for a moment. Would any real group of oppressed people needing the support of world opinion to affect change intentionally set out to commit such an horrific atrocity that it destroys that very support?
Let us say that Nation A is being cruelly oppressed by Nation B. Nation A has succeeded in winning world sympathy and support for the harsh and cruel treatment they suffer at the hand of Nation B. Then all of a sudden, there is a "terror" attack, and it look like Nation A has struck out at Nation B, killing a lot of innocent people. World sympathy for Nation A vanishes in an instant and shifts over to Nation B, the perceived victim.
Why would Nation A do such a stupid thing?
The truth is, nation A would not do such a thing. The benefit of the terror attack points to the real culprit, which is Nation B engaging in what is called a "False Flag: attack; committing an act of atrocity in order to blame it on the enemy.
Examples of false-flag attacks would include the bombing of the King David Hotel in 1946, carried out by members of Irgun dressed as Arabs, the Lavon Affair in 1954, carried out by Israeli agents but blamed on Egypt, and the attack on the USS Liberty in 1967, which had it succeeded, was also to be blamed on Egypt.
Nation A is, of course, Palestine, and Nation B is Israel, and it began to be obvious that there was a pattern in the so-called "terrorist" attacks which always seemed to occur just when public opinion was starting to favor the Palestinians, just in time to thwart the Palestinians' desire for a nation of their own, always just in time to swing world opinion back to Israel's continuing theft of Palestinian lands.
So who are the terrorists really working for?
