Why did the Israeli army attack Gaza?

First of all, Gaza is not a country, but a region. The main population of Gaza is Palestinians. Originally, the Palestinians wanted to establish a Palestinian state, but it has not been built yet.

Before World War II, there was no such country as Israel. Now this place called Israel is mostly inhabited by Palestinians. After World War II, the United Nations passed a resolution saying that an Israeli state should be established in this place, where all Jews can live. So the Palestinians think that the Israelis have robbed their territory, so they always want to come back. In the past, Palestine was supported by many Middle Eastern countries (because they were all Arabs and believed in Islam), and it was only after five wars with Israel that it was eliminated. But Israel, with its back to the United States (there are many Jews in the United States), has not been wiped out, but has occupied many Arab territories. Later, those countries in the Middle East decided that they could not beat Israel, so they stopped fighting.

But there is a Palestinian organization called Hamas, whose purpose is to kill Israel, so it always quarrels with Israel. There are two main ways to make trouble now. One is to let the death squads tie bombs to their bodies and rush into an Israeli restaurant. Boom died when they pulled the string. I don't know where I got the technology in the last two years, but I learned to make rocket launchers. Gaza fired rockets at Israelis from time to time.

From June, 5438 to February, 2008, Hamas was addicted to launching rockets, and fired dozens of rockets at Israel in one breath. The Israelis couldn't stand it anymore, so they slept with Hamas.
