Wellllllllllllll, my close relative who worked around them strongly disagrees with you.
A LOT of sources over the years have cited scrutiny of our Nuke industry and stores and missles.
The neutralizing of some of our silo'd missles in one famous case has been well researched and appears to have happened as multiple witnesses have claimed.
Some go so far as to assert that setting of nukes somehow disrupts different dimensions causing ET's trouble in a number of unknown ways.
Then there's the assertion that they just don't want such destructiveness loose amongst the galactic clusters.
Gee, what's the saying....What's that your smoking?? Are you into New Age Religion, too???
