Have there ever been any conspiracy theories that turned out to be true?

9/11
Look into tower #7
didnt believe the conspiracy yapping dogs before I actually researched it myself, mostly its the lack of destructive force and how fast all towers fell but there are many reasons why if you look, you will agree, it was not airplanes that made the buildings fall.

edit:
Come to think of it.. theres probably quite a few of them
Agent orange during vietnam
water gate
deep throat
W.M.D.s
and those were just the ones in the media… = [

But people like their perspective, if they didnt, they would probably research it themselves.

Many people are likely to post here with their own favourite unproven conspiracy theory, which will no doubt be useless to you in trying to convince your parents. Here are some real occurances which were originally considered to be conspiracy theories:

A famous scandal which began as a conspiracy theory was the Watergate affair. It began as a conspiracy theory about a hotel break-in, but ended up being traced to the highest levels of the American government, and it forced the resignation of President Nixon.

Other real conspiracy theories include:
- the French government's cover-up of the Dreyfus affair,
- Operation Himmler, where attacks were faked against German soldiers on the Polish border to justify the 1939 invasion,
- MKULTRA, the CIA's attempt to create and use mind control drugs,
- Operation Northwoods, again the CIA, this time committing violent acts which were then blamed on Castro
- Iran-Contra, where weapons were sold illegally to Iran to finance anticommunist rebels in Nicarauga
- the Tuskegee Study, where African-Americans were deliberately made unable to access treatments for syphillis to see the long-term effects of the disease
- the Streetcar Conspiracy, where GM and other auto industry companies began secretly purchasing streetcar lines, dismantled them, and replacing them with buses.

If it is a consipiracy theory than it has not been proven to be true. If it has been proven then it is a fact. Right?
