Hamas has demonstrated that they choose war with Israel over economic development and negotiation. Does any of the previous writers (except #4 who knows his history) remember that Israel tried to negotiate border and trade arrangements with Hamas when Israel withdrew from Gaza. The Hamas response was to bomb the jointly operated industrial zone and the border crossings. It is Hamas that refused trade arrangements with Israel. Go back and read the newspapers. Its even in Haaretz.
