the MiG-25 Foxbat, which the authors say flew sorties over Dimona shortly before the Six Day War

Had the MiG-25 even been deployed at the time of the 6 day war? I know the prototypes pre-date that, but I don't think it was in service by that point.

So at this point, I'm not sure I'm ready to swallow his theories.

I dug this out, for what it’s worth:

Series production of the two initial variants, designated MiG-25P (’Foxbat-A’) (interceptor) and MiG-25R (’Foxbat-B’) (reconnaissance), began in 1969. The MiG-25R entered VVS service almost immediately, but the service entry of the MiG-25P with the PVO was delayed until 1972.

According to Wikipedia (I know, I know) the Mig-25 first went into operational service in 1970. It is, however, possible, that individual aircraft were operational in 1967.
