Expose the U.S. Governments evil plots against America.

Is the U.S. Government, with the cooperation of Roswell collecting alien technology such as weaponry, alien flight technology, etc. to use not just to combat against alien threats, but to use to create a new world order? It seems so with all the reports of people who had encounters and were told to stay quite about it, as well as some air force pilots that were threatened have their careers taken away.
