The video making its way around my social-media feed Monday morning was harrowing: the execution of three Palestinians in Gaza deemed by Hamas to have “collaborated” with Israel.

“This recording is not accidental,” wrote Joe Truzman, an expert on Palestinian militant groups with the Foundation for Defense of Democracies. “While many clips show Hamas-linked operatives beating and shooting Palestinians in the limbs, filmed executions are comparatively rare. And when they are released deliberately, they serve a purpose.”

Hamas wanted Palestinians — and the world — to see these cold-blooded murders, and to see it now.

Meanwhile, at 11 a.m. London time in Hammersmith, throngs of members of the British parliament congratulated the Palestinian ambassador, Husam Zomlot, at a flag-raising event to mark the United Kingdom’s recognition of the “state of Palestine.”

“This solution is not a reward for Hamas,” UK Prime Minister Keir Starmer insisted Sunday even as Hamas celebrated.

That contradiction might as well be the theme of this week’s United Nations gathering in New York, where the official recognition announcements are taking place. France followed Britain, Canada and Australia on Monday.

Of course, Starmer and others toss in the occasional throwaway line about the hostages. But there is no action being taken on their behalf, no meaningful threats made to Hamas. Indeed, the day before the UK’s recognition of “Palestine,” Hamas released a “parting list” of all 48 who remain in captivity, and replaced each hostage’s name with that of Ron Arad — an Israeli airman kidnapped four decades ago in Lebanon and never found.

Meanwhile, Hamas responded to France’s recognition on Monday by releasing a new propaganda video of one of the hostages, Alon Ohel, as Israel prepared to observe Rosh Hashanah, one of the holiest days on the Jewish calendar.

Hamas is taunting the world while collecting its winnings.

Mandy Damari, mother of the freed hostage and UK citizen Emily Damari, castigated Starmer for “rewarding Hamas” at a time “when the hostages are still not back, the war is not over and Hamas are still in power in Gaza.”

It’s not just Hamas that’s getting a clear message from world powers this week — it’s the Palestinian people more broadly. After all, Palestinians in Gaza and in the West Bank are well aware that nothing Mahmoud Abbas and his government has done ever earned them statehood recognition from important European leaders.

Hamas did that — by making Oct. 7, 2023, the deadliest day for Jews since the Holocaust.

Spill enough Jewish blood and you get what you want — that’s the lesson.

Hamas is supposedly isolated from Western powers, and yet it is more effective at getting concessions from those very countries.

When Israel attempted to strike a meeting of high-level Hamasniks in Qatar, Starmer and Macron were right there to criticize Israel.

Hamas has thoroughly coopted the UN’s humanitarian-aid system, getting fat off of free food that was supposed to go to hungry Gazans. When a US-backed group threatened to break the UN’s monopoly, Hamas protested — and so did all these same Western leaders. Whose side are they on?

Less than three weeks ago, amid reports of widespread hunger in Gaza, Hamas released videos and images of two remaining hostages who were visibly being starved to death. The world said everybody in Gaza, civilians and hostages, deserved to eat. Well, food soon flooded back into the enclave and into the hands of Gazans, yet we have seen no evidence that the hostages have been treated any better. Lesson: Hamas is allowed to starve the hostages but Israel must feed Hamas.

On Tuesday, the UN Security Council is scheduled to meet about the conflict in Gaza. Israeli delegates won’t be there because it’s Rosh Hashanah.

True, Hamas won’t be there either — but the room will be full of diplomats speaking on its behalf. The hostages will have no such luck.
