The four most famous intelligence agencies in the world?

Mossad in Israel, CIA in the United States, MI5 in Britain and KGB in the Soviet Union are recognized as the four spy seas in the world.

Israel Mossad

The full name is Israel Intelligence and Special Mission Bureau, which was formally established at the beginning of 195 1, formerly known as the Political Department of the Ministry of Foreign Affairs. Israel's National Secret Service is the first intelligence agency in the world to apply computer technology. It cooperates closely with the CIA, but Israel has never publicly acknowledged the existence of Mossad. Mossad was formed with the development of Zionism and the establishment of the State of Israel. Before Israel's independence, there was a secret Jewish military organization "Hagana" (meaning "defense") in the Palestinian area. The purpose of its establishment was to secretly buy weapons, smuggle weapons and organize illegal Jewish immigration in the Palestinian area. For these activities, the intelligence agency "Shaya" affiliated to "Hagana" collected information.

United States central intelligence agency
