Like him or not, Ben Gurion had the foresight to bridge the very Left wing (MAPAI party-Haganah) to the very Right wing (Herut Revisionist party -Irgun-ETZEL-STERN) in order to forge a united, new nation - Israel.
There were seeds of civil war but Jewish leaders knew this was their make or break moment, something they waited for for 2,000 years and they had to (by force) put down any sedition to their authority in order to face the coming Arab onslaught.
The Irgun and Stern were absorbed into the Haganah in order to form the nascent Israel Defense Forces (Tzhahal). It worked.
The UN has been sorry the Jews survived ever since and have done everything in their power to weaken Israel.
The UN is a very sorry organization. The one bit of good they ever did, and they are ashamed of it. But they’re great at standing around and doing nothing while horrible atrocities are happening, and buggering out when their peace keeping missions suddenly turn hot.
