In ancient times, both Israelis and Palestinians (Arabs) established their own countries in this region (now Israel and Palestine). Later, Israelis (actually Jews) scattered around the world and were massacred by the Nazis in World War II. After World War II, because Jews were smart and had consortia in the United States, the United States supported the Zionist movement and transported a large number of Jews back to this land, gradually forming the opposition and hatred between Jews and Arabs. At that time, because the United Nations was dominated by the West, led by the United States, it was unfair to Arabs to adopt a resolution of independent statehood. The resolution gave 52% of the relatively fertile land in the region to a few Jews, while 48% of the land containing many deserts was given to a large number of Palestinians. Because it is unfair to Palestine, the Palestinians refused to accept this resolution and did not establish a country. The Jews agreed to this resolution and established the present Israel.
Of course, things will not end so simply. In the following decades, there were several wars, between Jews and Arabs. Of course, many Arab countries helped Palestine, while Israel was supported by the United States, Britain and France and even sent troops directly. The result was a victory for Israel. Therefore, he once occupied the Sinai Peninsula (Egypt), occupied the Syrian Golan Heights and many Palestinian lands, and established Jewish settlements on these lands.
There are two non-governmental armed forces in Palestine, Fatah and Hamas. Among them, Hamas is a radical Palestinian organization, which aims to expel Jews by force and often launches suicide attacks and rocket attacks. This problem is also caused by rocket attacks in Hamas. As of.1.2, 2009, more than 400 people were killed and more than 2,000 injured. Many Hamas sites in Gaza were bombed, nizar rayan, a senior leader of Hamas, was killed, and Hamas threatened to retaliate.
That's all I know. I don't know if you are satisfied.
