the six-day war of 1967
There have been numerous wars in Israel and the same territory prior to Israel's establishment.
Israel captured territory in every war it has fought. It was not required to immediately return the territory to its original holder in both the Six Day War of 1967 and the Lebanese Civil War of 1975-1991.
If you are talking about the settlements in the occupied territory it is because that is the territory that Israel claimed after the 5 day war in 1967.
The Sinai Peninsula.
According to historians, Israel gained the following lands as a result of war in 1948: Jaffa, Ramie, Lydda, Galilee and Negev. These lands were located in Arab territory.
Israel has been through numerous wars. The question needs to be more specific.
Prior to 1948, the territory that is now Israel was the British Mandate of Palestine. Britain had taken over the mandated territory from the former colonial power, Turkey, following the First World War and was close to granting independence to the Palestinians when the Jews decided to resolve matters in their own favour.
Most of the land known as Palestine became Israel in 1948, following the end of the British Mandate for Palestine and the subsequent declaration of the State of Israel on May 14, 1948. This event led to the first Arab-Israeli War, resulting in the establishment of Israel and significant territorial changes. By the end of the conflict in 1949, Israel had expanded its territory beyond the borders proposed in the 1947 UN Partition Plan.
In Israel, Egypt, and Syria. Egypt and Syria attacked Israel by surprise; at the beginning of the war, when Israel was losing, the Syrians had pushed through most of the Golan Heights* (destroying nearly every civilian structure they came across and menacing the most populated part of Israel, which is right below the Golan), while the Egyptians had overwhelmed Israeli defenses along the Suez Canal and entered the Sinai Peninsula**. (It should be noted that while the Golan is still Israeli territory, the Sinai has now been returned to Egypt.) By the end of the war, however, when Israel (with indirect US aid) had turned the tide, Israeli forces had entered Syria and menaced Damascus, while crossing the Suez, cutting off most of the Egyptian army, and approaching Cairo. The war ended when the USSR, an Egyptian ally, threatened to use nuclear weapons on Israel. Even though Israel at the time had just begun its own nuclear program, it did not want to disclose that fact, and probably didn't have the delivery systems to adequately deter the USSR anyway. *Territory in Northwestern Israel captured from Syria in 1967. **A large swath of biblically-mentioned desert captured from Egypt in 1967.
The simple answer is "Yes" and many of them still want it destroyed, but have realized that Israel's destruction will not come through a conventional war since Israel is far better armed than most Arab States.
Syria lost territory to Israel in the 1967 War (the Golan Heights). It made no successful incursions into Israel from that point onwards. The Syrian Army did invade Lebanon in 1982 and occupied Lebanon until 2006.
No, Israel is not part of Syria; it is an independent country established in 1948. However, there are disputed territories, such as the Golan Heights, which Israel captured from Syria during the 1967 Six-Day War and later annexed. This annexation has not been recognized by most of the international community, and Syria still claims the Golan Heights as part of its territory.
