The State of Israel
declared its establishment on 14 May 1948. The armies of neighboring Arab states invaded the area of the former Mandate the next day, beginning the
First Arab–Israeli War. Subsequent
armistice agreements established Israeli control over
77 percent of the former Mandate territory.
[26][27][28] The majority of
Palestinian Arabs were either
expelled or fled in what is known as the
Nakba, with
those remaining becoming the new state's main minority.
[29][30][31] Over the following decades, Israel's population increased greatly as the country received an influx of
Jews who emigrated, fled or were expelled from the Muslim world.[32][33] .....
Note that the Jews fled/expelled from the Muslim world almost at same time as Palestinian Arabs left Israel.

Further History and Context:
....
During the 1950s, Israel was
frequently attacked by
Palestinian fedayeen, nearly always against civilians,
[198] mainly from the Egyptian-occupied Gaza Strip,
[199] leading to several Israeli
reprisal operations. In 1956, the UK and France aimed at regaining control of the
Suez Canal, which Egypt had nationalized. The continued blockade of the Suez Canal and
Straits of Tiran to Israeli shipping, together with increasing fedayeen attacks against Israel's southern population and recent Arab threatening statements, prompted Israel to attack Egypt.
[200][201][202] Israel joined
a secret alliance with the UK and France and overran the
Sinai Peninsula in the
Suez Crisis but was pressured to withdraw by the UN in return for guarantees of Israeli shipping rights.
[203][204][205] The war resulted in significant reduction of Israeli border infiltration.
[206]
....
In May 1967, Egypt massed its army near the border with Israel, expelled
UN peacekeepers stationed in the Sinai Peninsula since 1957, and blocked Israel's access to the Red Sea.
[216][217][218] Other Arab states mobilized their forces.
[219] Israel reiterated that these actions were a
casus belli and launched a pre-emptive strike (
Operation Focus) against Egypt in June. Jordan, Syria and Iraq attacked Israel. In the
Six-Day War, Israel captured and occupied the West Bank from Jordan, the Gaza Strip and Sinai Peninsula from Egypt, and the Golan Heights from Syria.
[220] Jerusalem's boundaries were enlarged, incorporating East Jerusalem. The 1949 Green Line became the administrative boundary between Israel and the
occupied territories.
[221]
Following the 1967 war and the "
Three Nos" resolution of the Arab League, Israel faced attacks from the Egyptians in the Sinai Peninsula during the 1967–1970
War of Attrition, and from Palestinian groups targeting Israelis in the occupied territories, globally, and in Israel. Most important among the Palestinian and Arab groups was the
Palestine Liberation Organization (PLO), established in 1964, which initially committed itself to "armed struggle as the only way to liberate the homeland".
[222] In the late 1960s and early 1970s,
Palestinian groups launched attacks[223][224] against Israeli and Jewish targets around the world,
[225] including
a massacre of Israeli athletes at the
1972 Summer Olympics in Munich. The Israeli government responded with an
assassination campaign against the organizers of the massacre,
a bombing and a
raid on the PLO headquarters in Lebanon.
On 6 October 1973, the Egyptian and Syrian armies launched
a surprise attack against Israeli forces in the Sinai Peninsula and Golan Heights, opening the
Yom Kippur War. The war ended on 25 October with Israel repelling Egyptian and Syrian forces but suffering great losses.
[226] An
internal inquiry exonerated
the government of responsibility for failures before and during the war, but public anger forced Prime Minister
Golda Meir to resign.
[227][
better source needed] In July 1976, an airliner was hijacked in flight from Israel to France by Palestinian guerrillas; Israeli commandos
rescued 102 of 106 Israeli hostages.

As can be seen, Israel has been under constant attacks and threats of such since it's founding in 1948.
Israel's enemies do not want real peace with Israel and want Israel extinguished.
