If you google French government and UFO you will find articles where the French government believes in UFOs. If you google Canadian government minister and UFOs you will fimd that Canada believes in UFOs and aliens. However, with the US, there is a deafening silence on what it knows about UFOs and aliens.
Why?
One can only speculate just as one speculates what goes on in Area 51. The obvious answer is the technology involve if ever there was or are encounters with aliens.
Such speculation however casts one in a different light. The US - through the CIA - has successfully developed a mechanism where individuals who believe in UFOs and aliens are labelled as conspiracy theorists even though other foreign governments acknowledge the existence of UFOs.
