Israel has been at war since 1948. It doesn't represent a threat to its neighbours unless its own territory is attacked, a territory established by the United Nations through Resolution 181.
Zionist terror gangs (Haganah, Irgun, Stern Gang, Lehi) were waging war in Palestine from the 1920's onwards. Zionist terror gangs were responsible for the first bus bombing, cafe bombing, first hostage taking plus many other notable "firsts". The leader of the Haganah (Zionist terror group founded 1920-note the date) was David Ben Gurion. I'm sure that you have heard of him, Israel's first PM and has an airport named after him. These Zionist terror gangs were European Ashkenazi Jews. The descendants of the biblical Jews already lived in Palestine. It was European interlopers that introduced terrorism to Palestine as an undisputed fact.
"
At a meeting of Haganah leaders in Tel Aviv in March, 1948, and with Ben-Gurion present, it was decided to draw up a comprehensive plan for ethnic cleansing, known as “Plan Dalet”, according to which numerous massacres were carried out to terrorize the Palestinian civilian population and to drive them out of their homeland. Some massacres were carried out before the creation of the Israeli army, as in the Tantura massacre, a village south of Haifa, on 22 and 23 May, 1948, which resulted in the killing of more than 200 Palestinian men and women. Others were committed after that army was formed, as in the village of al-Dawaymah in the al-Khalil (Hebron) district, on October 29, 1948, where hundreds of Palestinian men and women were killed."
The Haganah on the Israeli declaration of statehood became the IDF. Israel is a terrorist state, born from terror and surviving on terror ever since.
