It started on a Saturday. Most people remember exactly where they were when the news pings began hitting their phones on October 7, 2023. It wasn't just another flare-up in a region that has seen far too many of them. This was something different. If you’ve been trying to wrap your head around why did Israel attack Gaza with such unprecedented force, you have to look past the immediate headlines and dig into a mess of security failures, historical trauma, and geopolitical shifts.
The short answer? Hamas.
The long answer is much more complicated. It involves decades of blockade, a massive intelligence failure that embarrassed the Israeli Mossad and Shin Bet, and a fundamental shift in Israeli military doctrine from "containment" to "elimination."

The October 7 Trigger Point
You can’t talk about the current war without talking about the bridge that burned. On October 7, Hamas—the militant group that has governed the Gaza Strip since 2007—launched a massive, multi-pronged assault on southern Israel. They called it "Operation Al-Aqsa Flood."
It was brutal.
Hamas fighters breached the high-tech border fence, using paragliders, motorcycles, and boats. They attacked music festivals like the Supernova gathering and several kibbutzim. By the end of the day, roughly 1,200 Israelis were dead. Most were civilians. Another 240 or so were taken back into Gaza as hostages. For Israel, this wasn't just a terror attack; it was an existential shock. It was the deadliest day for Jewish people since the Holocaust.
Basically, the Israeli government felt it had no choice but to respond in a way that ensured Hamas could never do it again. Prime Minister Benjamin Netanyahu made it clear: the goal was the "total destruction" of Hamas’s military and governing capabilities.
Why Did Israel Attack Gaza Now and Not Before?
People often ask why this specific war is so much more intense than the conflicts in 2008, 2012, 2014, or 2021. Those were "operations." This is a full-scale war.

Previously, Israel followed a policy often called "mowing the grass."
It’s a grim metaphor. It meant that every few years, Israel would strike Gaza to degrade Hamas's rocket stockpiles and tunnels, then settle back into a tense status quo. They thought they could manage the conflict. They thought Hamas was interested in governing Gaza more than starting a regional war. They were wrong.
The scale of the October 7 massacre proved that "containment" had failed. The Israeli public demanded a permanent solution. You've got to understand the shift in the Israeli psyche here—the feeling of safety was shattered. When a country feels its borders are porous and its citizens are no longer safe in their beds, the military response usually moves from "measured" to "total."
The Intelligence Failure
There’s also the "why" regarding the timing. Hamas spent years tricking Israel into thinking they wanted economic stability. They even stayed out of some smaller skirmishes between Israel and Islamic Jihad. While Israel was focused on domestic political protests and the West Bank, Hamas was training in plain sight.
When the attack happened, the Israeli Defense Forces (IDF) were caught off guard. This embarrassment fueled the intensity of the subsequent invasion. The military felt a desperate need to restore "deterrence." If Hezbollah in the north or Iran saw Israel as weak, the situation could spiral into a multi-front war.
Geopolitics and the "Iranian Axis"
Let’s zoom out. This isn’t just about a tiny strip of land 25 miles long.

Israel views Hamas as a proxy for Iran. For years, Iran has provided Hamas with funding, technical expertise for rocket manufacturing, and strategic guidance. By attacking Gaza, Israel is also sending a massive signal to the "Axis of Resistance," which includes Hezbollah in Lebanon, the Houthis in Yemen, and various militias in Iraq and Syria.
- The Saudi Factor: Before the war, Israel was on the verge of a historic peace deal with Saudi Arabia. This would have fundamentally changed the Middle East, sidelining the Palestinian cause. Many analysts believe Hamas attacked to derail this normalization, and Israel’s massive response was partly intended to show the Arab world that it remains the dominant military power in the region.
- The Tunnel Network: One specific reason for the ground invasion was the "Gaza Metro." This is a vast network of hundreds of miles of tunnels built under civilian infrastructure. Israel argued that air strikes alone couldn't destroy this "city under a city." To get rid of the threat, they had to go in on foot.
Human Cost and the International Outcry
While the "why" for Israel is rooted in security and the destruction of Hamas, the "how" has led to a global humanitarian crisis. Gaza is one of the most densely populated places on Earth. When you drop heavy ordnance in a place like Gaza City or Khan Younis, civilian casualties are inevitable.
The death toll in Gaza has surpassed 30,000, according to the Gaza Health Ministry. These numbers include thousands of children. This has led to South Africa filing a case at the International Court of Justice (ICJ) accusing Israel of genocide—a charge Israel vehemently denies, citing Hamas's use of human shields.
Honestly, the complexity is staggering. On one hand, you have Israel's right to defend itself after a heinous massacre. On the other, you have millions of civilians in Gaza with nowhere to go, caught between a militant group that embeds itself in schools and hospitals and a military determined to root them out at any cost.
The Hostage Dilemma
Another huge part of why did Israel attack Gaza—and why they stayed—is the hostages.
Families in Tel Aviv and across the world have been campaigning for the release of their loved ones for months. The Israeli government has used military pressure as a lever to force Hamas into negotiations. The logic is: "We won't stop until they are home." However, as the months drag on, many in Israel are starting to wonder if the military campaign actually puts the hostages' lives at greater risk.
What Most People Get Wrong About the Conflict
It's easy to look at this as a simple "good vs. evil" story depending on which news channel you watch. But there are layers here that rarely get mentioned in a 30-second soundbite.
- It’s not just about religion. While there are religious extremists on both sides, this is primarily a nationalist and territorial conflict. It's about who gets to live on the land and under what kind of sovereignty.
- The "Blockade" context. Gaza has been under a blockade by Israel and Egypt since 2007. Israel says it’s to prevent weapons smuggling; Palestinians say it’s a form of collective punishment that turned Gaza into an "open-air prison." This environment created a pressure cooker that eventually exploded.
- The Internal Politics. Both Netanyahu and Hamas leaders have political reasons to keep the conflict going. Netanyahu faces multiple corruption trials and a fractured coalition; a wartime footing keeps him in power. Hamas, meanwhile, uses the "resistance" narrative to maintain its grip on power despite the suffering of Gazans.
Moving Beyond the "Why"
So, where does this leave us? The war has fundamentally changed the Middle East. The idea that the Palestinian issue could be "managed" or ignored is dead.
If you are trying to understand the situation more deeply, don't just look at the daily casualty counts. Look at the maps. Look at the proposed "Day After" plans. Israel wants a demilitarized Gaza where they maintain security control, similar to the West Bank. Hamas wants to survive as a political entity. The international community, led by the U.S., is pushing for a two-state solution that seems further away than ever.
Actionable Insights for Following the Conflict:
- Diversify Your News Sources: Don’t rely solely on social media or a single news outlet. Compare reporting from Al Jazeera (which focuses heavily on the Palestinian perspective), The Times of Israel (which provides deep internal Israeli context), and neutral agencies like Reuters or AP.
- Check the Maps: Use resources like the Institute for the Study of War (ISW) to see the actual territorial gains and losses. It helps you understand the military "why" versus the political "why."
- Follow the Money: Look into how Gazan reconstruction is being discussed. The involvement of Qatar, the UAE, and the U.S. in future funding will tell you more about the eventual outcome than the current bombs will.
- Understand the Legal Terms: Learn the actual definitions of "proportionality," "collective punishment," and "genocide" under international law. These terms are often used incorrectly in heated debates.
The situation remains fluid. As of early 2026, the scars of this specific chapter are still being written, and the geopolitical ripples will be felt for a generation. Understanding that this wasn't just a random act of aggression—but the result of a massive security collapse and a long-standing, unresolved territorial struggle—is the first step in making sense of the chaos.
