Can you imagine the USA let foreign teams go to some high secuity level place like "Area 51"? Maybe my thought is not the fact,but at that very time,I dont think any country would have the time to care about such things and act quickly.I think the offer and acceptance of help by gov. are more as diplomatism affairs,not that simple logic of good or bad.
“Area 51” in our country is a joke. We have people that believe that the bodies of alien beings from outer space are kept there and many other silly things.
When we think people are believing crazy things we say they need to start wearing tin foil hats. That is because in the old days when a schizophrenic patient was having paranoid delusions, the psychiatrist would tell them they could block the voices they were hearing in their head by putting on a tin foil hat, so they would receive radio waves from the C.I.A. that were driving them crazy. That was the delusion of the paranoid schizophrenic patient to explain to themselves why they were hearing voices, and the advice by the psychiatrist about wearing a tinfoil hat was meant to calm them. This was before we had good medicines for schizophrenia. (Tin foil is an old name for aluminum foil, which we use for cooking.)
I am sure we have places in the U.S. where we work on advanced secret military planes and equipment, but I doubt it is done at “Area 51” any more.
But the logic is good. The more healthy people helping the sick, the more sick people survive.
You should read this speech by a Canadian radio broadcaster in 1973. Americans are good people.
