Under BN no, I don't think peaceful protest would win political ends.
But I do 100% think it would mean less retaliatory violence, even under BN.
And I honestly think if Palestinian leadership were to put out a statement on behalf of both Gaza and WB that there would be no more violence and Hamas were gone, hostages returned, and for say for example 6m; no rockets, no bombs, no terrorism, no shootings, peaceful delegations sent to the USA and Europe to advocate the Palestinian cause, international pressure would be such that a real peace process to a 2ss could start.
The constant use of violence isnt working for Palestinians is it? In neither Gaza or the WB are their lives improving.
They should try another way. Its their future, after all. Israel is taking care of its own. Palestinian leadership should try the same. I think under a moderate leadership next year, they could get their homeland.
