Why did Israel perish in history?

Israel is a country located in the Levant region of West Asia, on the southeast coast of the Mediterranean Sea, bordering Lebanon in the north, Syria and Jordan in the east and Egypt in the southwest. 1948 declared Israel and Jerusalem as the capital of Israel.

King Solomon, the son of David, split into two countries in the 10 century BC, namely, the kingdom of Israel, which is composed of ten tribes in the north, and the kingdom of Judah, which was inherited by David's descendants in the south. In 722 BC and 586 BC, the two kingdoms were conquered by Assyrians and destroyed by Babylonians respectively. Most Jews were captured in the two river basins and did not return in batches until the Persian Empire.

The author thinks that the reason why Israel perished in history is that the Israeli people are not United enough, the population is small, the economic and technological strength is not strong enough, the national consciousness is not strong enough, and there is no foreign aid.
