Or wanted to find out whether the Russians would detect it.
It's admittedly a wild theory, but what if the US and Israel chose to not announce the test, in order to see how the Russians would react?
The US may have had the area blanketed with electronic warfare aircraft with the express purpose of monitoring their reaction.
“It’s admittedly a wild theory, but what if the US and Israel chose to not announce the test, in order to see how the Russians would react?”
It’s not a wild theory. During the so called Cold War, both sides did things/tests to monitor if the other side was monitoring and what their response was.
It today’s electronic world, anything is possible.
“—may have the area blanketed-—” Oh, Yeah! The USS Mt Whitney is always in the area and that thing is a regular sea-going Radio Shack. Not to mention but the crew on that thing would have known EXACTLY what was going on in Benghazi.
