You might add, that the rocket attacks increased after an Israel raid mistakenly killed (by their own admission) the son of a prominent Hamas leader.

And, that Hamas threw out Fatah because Bush was building up Fatah forces in hopes that Fatah would overthrow Hamas.

key word: increased. implies previous level of existence.

There is no legitimate reason under transparent interpretations of democracy for one party to violently expel another from government. that is a coup.
