According to a survey by Kapa Research published in the center-left newspaper
To Vima in 2002, the majority of the electoral body (54.7%) consider the regime to have been bad or harmful for Greece while 20.7% consider it to have been good for Greece and 19.8% believe that it was neither good nor harmful. In April 2013, the Metron Analysis Poll, found that 30% of Greeks yearned for the ´better´days of the Junta. (from wiki but still a quote from a published report)
The Junta outcome was similar to what happened to the Argentinian Junta that collapsed after the Falklands War.
To answer the question though, normally when a country (Turkey) invades your land (Cyprus), it galvanizes the public (in this case Greece) to be very patriotic. In fact, when the invader outnumbers the defenders (40,000 to 10,000), then the public normally becomes very sympathetic to the underdog (Cypriot National Guard).
