Take a look at this article Abbas: Armed 'resistance' not ruled out
PA President Mahmoud Abbas on Thursday said that he does not rule out returning to the path of armed "resistance" against Israel and took pride in the fact that he had been the first to fire on Israel and that his organization had trained Hizbullah.
"At this present juncture, I am opposed to the armed struggle because we can't succeed in it, but maybe in the future things will be different," he said.
In other words, the so called "peace process" is a complete and utter fraud. The Palestinians realized that they can't win a war so now they are trying to get what they can in a different way, however, fundamentally , they believe in "armed struggle".
Here is another great quote
"I had the honor of firing the first shot in 1965 and of being the one who taught resistance to many in the region and around the world; what it's like; when it is effective and when it isn't effective; its uses, and what serious, authentic and influential resistance is," Abbas said.
The bottom line is that there is very little difference between Abbas, Arafat, Hamas, Hizbullah, etc. in terms of their ultimate goal, the destruction of Israel. The only difference is tactical, what is the best way to accomplish it.
