There's no reason to think that. They agreed to ammend the charter in 93, and have never so much as made an attempt.
Ever read their "phased plan" adopted in 1974 (lots of sources, on here: http://www.netaxs.com/~iris/plophase.htm). In brief:
1-Through the "armed struggle" (i.e., terrorism), to establish an "independent combatant national authority" over any territory that is "liberated" from Israeli rule. (Article 2)
2-To continue the struggle against Israel, using the territory of the national authority as a base of operations. (Article 4)
3-To provoke an all-out war in which Israel's Arab neighbors destroy it entirely ("liberate all Palestinian territory"). (Article 8)
They've never revoked this either. IMO, they think they're near the end of 1, establishing an "independent combatant national authority", in which they can consolidate Arab strength (sheltered by UN peacekeepers?) per step 2.
A lot has happened since 1974 (if I believed everything the U.S. government said 1974, I would be very unhappy now - which is the case).
Step 3 - To provoke an all-out war in which Israel's Arab neighbors destroy it entirely..
We are getting close to the all-out war part - which will result in major world upheaval no matter who "wins". Israel seems to be co-operating with this plan quite well.
