False flag attacks are not something that get discussed much when talking about the history of wars and conflicts. However, they have been used by governments for years to justify attacks on other countries, as well as create public support for whatever the authorities deem necessary to deal with the alleged/created threat.
Just what is a false flag attack? Here is an explanation on Wikipedia: “covert operations which are designed to deceive the public in such a way that the operations appear as though they are being carried out by other entities. The name is derived from the military concept of flying false colors; that is, flying the flag of a country other than one’s own.”
Here are just a few examples, including a couple involving the US. Many historians have even come to the conclusion that the Gulf of Tonkin Incident was a false flag attack orchestrated by the US, using old, empty destroyers as the targets, as a justification for the war in Vietnam. To my knowledge, this conclusion is unconfirmed, but being that the intelligence itself was skewed with documented proof of this fact, it seems at least possible these accusations could prove to be true.
The most interesting and quite startling false flag attack plan by the US that was thankfully never implemented was Operation Northwoods. When you read the information from that plan (PDF), you won’t believe your eyes.
