False flag-operation.. ?
Citat:
Today, however, the evidence for these alleged Soviet intrusions
appears to have been manipulated or simply invented. Classified doc-
uments and interviews cited in this book point to covert Western
rather than Soviet activity. This is backed up by former US Secretary
of Defense Caspar Weinberger, who stated, in a Swedish television
interview reproduced in this book, that Western ‘testing’ operations
were carried out regularly in Swedish waters, and by former British
Navy Minister Sir Keith Speed, who has confirmed the existence of
such operations.
