• Dissolving more of the barrier between Hamas as a political organization & as an insurgent organization
• Spitting in Israel's face who was hoping that a decapitation strike would leave hamas with a leader lacking broader political legitimacy in the organization or create divisions/deepen divisions between civilian governance & militant organization
• Lessens the leverage Qatar has over Hamas as they were providing Haniyeh with refuge
• Since Sinwar is (presumably) in Gaza, his presence will likely be used to justify decreasingly discriminate attacks even moreso than it was before
• Likely much more uncompromising (not to imply Haniyeh was) in negotiations
• Israel and the US will have to directly negotiate with someone they despise
• Dropsite News describes sinwar as such:

Despite the sinister portrayals, Sinwar’s writings and media interviews indicate he is a complex thinker with clearly defined political objectives who believes in armed struggle as a means to an end. He gives the impression of a well-educated political militant, not a cult leader on a mass suicide crusade. “It's not this black image of Sinwar as a man with two horns living in the tunnels,” said Hamad, the Hamas official who worked directly with Sinwar for three years. “But in the time of war, he's very strong. This man is very strong. If he wants to fight, he fights seriously.”

In 1988, just months after Hamas was founded, Sinwar was arrested by Israeli forces and sentenced to four life sentences on charges he had personally murdered alleged Palestinian collaborators. During his 22 years in an Israeli prison, he became fluent in Hebrew and studied the history of the Israeli state, its political culture, and its intelligence and military apparatus. He translated by hand the memoirs of several former heads of the Israeli intelligence agency Shin Bet. “When I entered [prison], it was 1988, the Cold War was still going on. And here [in Palestine], the Intifada. To spread the latest news, we printed fliers. I came out, and I found the internet,” Sinwar told an Italian journalist in 2018. “But to be honest, I never came out—I have only changed prisons. And despite it all, the old one was much better than this one. I had water, electricity. I had so many books. Gaza is much tougher.”[...]

Sinwar, unlike leaders of Al Qaeda or ISIS, has regularly invoked international law and UN resolutions, exhibiting a nuanced understanding of the history of negotiations with Israel mediated by the U.S. and other nations. “Let's be clear: having an armed resistance is our right, under international law. But we don't only have rockets. We have been using a variety of means of resistance,” he said in the 2018 interview. “We make the headlines only with blood. And not only here. No blood, no news. But the problem is not our resistance, it is their occupation. With no occupation, we wouldn't have rockets. We wouldn't have stones, Molotov cocktails, nothing. We would all have a normal life."

Throughout 2018 and 2019, Sinwar endorsed the large-scale nonviolent protests along the walls and fences of Gaza known as the Great March of Return. “We believe that if we have a way to potentially resolve the conflict without destruction, we’re O.K. with that,” Sinwar said at a rare news conference in 2018. “We would prefer to earn our rights by soft and peaceful means. But we understand that if we are not given those rights, we are entitled to earn them by resistance.”[...]

After the end of Israel’s 11-day bombing campaign against Gaza, Sinwar spoke to VICE News and sought to frame the Palestinian struggle in a U.S. context, using recent cases of lethal police violence against African Americans. “The same type of racism that killed George Floyd is being used by [Israel] against the Palestinians in Jerusalem, the Sheikh Jarrah neighborhood, and in the West Bank. And by the burning of our children. And against the Gaza Strip through siege, murder, and starvation.”

Support among Palestinians for Hamas and its Gaza leader Yahya Sinwar, according to the recent poll, “remains very high” and has increased during the past three months. At the same time, while two-thirds of Palestinians polled in the occupied territories believe that Hamas will “win the war,” only 48 percent of those in Gaza agreed.

Hamas has insisted the war cannot destroy its movement and will remain part of the tapestry of Palestinian factions governing its besieged and occupied territories. “What matters is that you finally realize that Hamas is here. That it exists. That there is no future without Hamas, there is no possible deal whatsoever, because we are part and parcel of this society, even if we lose the next elections,” Sinwar warned in 2018. “But we are a piece of Palestine. More than that, we are a piece of the history of the entire Arab world, which includes Islamists as well as seculars, nationalists, leftists.”

“Hamas is an idea, Hamas is a party. It’s rooted in the hearts of the people — anyone who thinks we can eliminate Hamas is wrong,” he continued.
