Today is an anniversary.. actually every day is an anniversary. If you think of the bloodshed humankind has visited upon each other there is no date which is not an anniversary of bloodshed. It seems, though, that September 11 has a peculiar history.
Of course everybody remembers this September 11: 1973: President overthrown in Chile coup right? President Salvador Allende of Chile, the world's first democratically-elected Marxist head of state, has died in a revolt led by army leaders. Except the BBC report does not say that the revolt was instigated by the U.S. Salvador Allende @ Wikipedia, Augusto Pinochet @ Wikipedia, 1973 Chilean coup d'état @ Wikipedia, Project FUBELT @ Wikipedia
And, the British Mandate of Palestine began on this date in 1922. This was part of the general occupation of the Middle East by Europe, especially Great Britain, following World War I. The Middle East had been ruled by the Ottoman Empire which crumbled in the wake of that war. The British had administrative control of Palestine and several other areas in the Middle East. I suspect it was the period of British control which led to a portion of the problems we're experiencing today stemming from the Middle East.
For instance I noticed in the Wikipedia that on September 11, 1921 (one year before the mandate began) Nahalal, the first moshav in Israel, is settled. A moshav is a similar concept to the Kibbutzim, but instead of being socialistic in nature (in a kibbutz nobody owns anything, the kibbutz owns it all) the moshav relies on shared ownership. The establishment of Nahalal was part of the early settlement of Palestine by the Jewish from Eastern Europe. The, uh, annexation of Palestine by the Jews leading to the establishment of Israel started much earlier than the mid 1940's.
And in a curious coincidence of history: 1941 - Ground broken for the construction of The Pentagon.
1978 - U.S. President Jimmy Carter, President Sadat of Egypt, and Prime Minister Begin of Israel met at Camp David and agreed on a framework for peace between Israel and Egypt and a comprehensive peace in the Middle East.
1982 - The international forces, which were guaranteeing the safety of Palestinian refugees following Israel's 1982 Invasion of Lebanon, left Beirut. Five days later, several thousand refugees were massacred in the Sabra and Shatila refugee camps.
1987 - Twelve people die in a shoot-out in Jean-Bertrand Aristide's church in Haiti
1990 - U.S. President George H. W. Bush delivers a nationally televised speech in which he threatens the use of force to remove Iraqi soldiers from Kuwait, which Iraq had recently invaded. He mentions the term "New World Order" in this speech for the first time, which is also named "Towards a New World Order".
1998 - Independent counsel Kenneth Starr sends a report to the U.S. Congress accusing President Bill Clinton of 11 possible impeachable offenses.
