How the English defended their people in WWII from V2 German rockets on London

How the English defended their people in WWII from V2 German rockets on London and how did the English-British fight mercilessly the IRA terror.
Israel must do no less.
The Europeans were complicit in the Holocaust of over 6 million Jews. They will not quiet down until Israel disappears.
The Mufti of Jerusalem was personally responsible and actively participated in the murder of 12,000 Jews in Europe during WWII.
The Jewish people are not going to be a scapegoat for anyone anymore. NEVER AGAIN.

Israel has defeated the Arab aggressors in 4 major wars (1948, 1956, 1967 and 1973) where in history have you seen the vanquished dictate the terms? Nowhere.
Let the defeated Arabs accept the peace offering Israel is offering them and proceed to improve the standard of living of their people, instead of wasting billions of dollars on war, terror and violence.
A true and lasting peace will bring a monumental economic prosperity to all the people in the region.
The State of Israel (which is a Jewish State) took care of the million Jews who were forced out of Arab countries their homes and assets confiscated (small in numbers with limited resources). It is about time the Arab countries (which numbers over a billion people and numerous resources) should take care of the displaced Arabs they created in Israel-Palestine.
