Israel's Foreign Ministry Arabic social media accounts published photos of the beginning of construction of the Israeli exhibition building at the Dubai Expo 2020.
Arabic news media follow those accounts closely and the news was widely spread.
Hamas read the stories and got very upset.
Spokesman Hazem Qassem issued a statement, "calling on the parties that seek to normalize with the occupier to stop this behavior.
"This (behavior) encourages the occupation to raise the pace of its crime against our Palestinian people and increase its violations against the sanctities of the [Islamic] nation.
"The Zionist entity must remain the central enemy of the nation, maintaining the conflict with it, and facing its policy that aims to undermine all opportunities for the nation's rise and development."
It wasn't that long ago that Hamas or the PLO could issue a statement like this and the Arab world would be shamed into following their demands. Those days are now over, and the Palestinians who have rejected peace for so long as their main tactic, knowing that the Arab world backed them up, have no ideas what to do.
Because actually negotiating in good faith is not imaginable to them.
