From July 21 - 31, Joint Task Force (mostly US, but also UK, Brazil and Italy) "Operation Brimstone" large scale war games were conducted off the US East coast in the North Atlantic. Its purpose may have been to prepare for a naval blockade of Iran. Initial reports after its completion were that participating ships were deployed to Persian Gulf and Arabian and Red Sea locations to join up with the present American strike force in the region. The major media cover none of this, and US Navy sources deny it. So precise information is unclear. From what's known, however, redeployment may be planned, and a blockade may ensue. The situation remains tense and worrisome.
This would be one way of attempting to provoke an attack by Iran, or having some kind of "false flag" operation happen, then blaming it on Iran
