After doing some research I now have a better understanding of what happened years ago that has led to this hate between the two sides. Granted Wikipedia is not the best of sources to go by but I'm sure most of the stuff can be verified by other outlets as well.
The UN General Assembly approved the 1947 UN Partition Plan dividing the territory into two states, with the Jewish area consisting of roughly 55% of the land, and the Arab area roughly 45%.
Immediately following the adoption of the Partition Plan by the UN General Assembly on November 29, 1947, David Ben-Gurion tentatively accepted the partition, while the Arab League rejected it. Attacks on civilians by both sides soon turned into widespread fighting between Arabs and Jews
Following the State of Israel's establishment, the armies of Egypt, Syria, Jordan, Lebanon, and Iraq joined the fighting and began the second phase of the 1948 Arab-Israeli War. From the north, Syria, Lebanon, and Iraq, were all but stopped relatively close to the borders. Jordanian forces, invading from the east, captured East Jerusalem and laid siege on the city's west.
On July 7, 1981, the Israeli Air Force bombed the Iraqi nuclear reactor at Osiraq in an attempt to foil Iraqi efforts at producing an atom bomb.
In 1982, Israel launched an attack against Lebanon, which had been embroiled in the Lebanese Civil War since 1975. The official reason for the attack was to defend Israel's northernmost settlements from terrorist attacks, which had been occurring frequently. However, after establishing a forty-kilometer barrier zone, the IDF continued northward and even captured the capital, Beirut.
The IDF is one of the best funded military forces in the Middle East and ranks among the most battle-trained armed forces in the world, having been involved in five major wars and numerous border conflicts. In terms of personnel, the IDF's main resource is the training quality of its soldiers and expert institutions, rather than sheer numbers of soldiers. It also relies heavily on high-tech weapons systems, some developed and manufactured in Israel for its specific needs, and others imported (largely from the United States).
The International Atomic Energy Agency believes Israel to be a state possessing nuclear weapons. The government has never confirmed nor denied this assertion. Israel has not ratified the Nuclear Non-Proliferation Treaty and the Chemical Weapons Convention (CWC) and is not a signatory to the Biological and Toxin Weapons Convention (BWC).
