To prevent money from ending up in the hands of Hamas?
To prevent Hamas from buying more rockets and weapons with that money?
Because there is a naval blockade in place right now because Gazans have elected people (Hamas) to represent them who believe in this:
You are making it much more difficult than it has to be....heck even Netanyahu , Obama , and Abbas understand this....
Hamas must renounce the Covenant, agree to negotiate, and give up the "jihad is the only solution" clauses in their platform. Period.
If they did that, I firmly believe Israel would have no choice but to acknowledge them as a state, and end the blockade.
Really, its up to the Palestinian people...
