Erdogan is getting the upper hand in the internal struggle with the Generals. Islamists (like Erdogan) are on the rise since a number of years and Kemalists (secular) like what the TGS used to be are on the down or in alignment with Erdogan after the recent purges/appointment of favourable sons...
This can get interesting, fast, indeed.
As for a land invasion, that of course is a joke. An air-sea operation is another matter and one that would be equally serious, if it were to happen. Turkey have lost quite a lost of face over the flotilla event and Erdogan hasn't forgot...he needs to restore his new-Ottoman course to the perceived strength that he already had before this unfortunate chain of events.
Having said that, not unfortunate for Greece as it turns out who have already gone some way towards a strategic alliance with Israel in the last two years with a number of exercises having been carried out already. By the way, Greece have declared through the governement Vice President that any possible Turkish moves towards Cyprus won't go unaswered, in response to Turkish threats on the imminent natural gas enterprise between Cyprus and Israel.
Definitely, interesting (and worrying) developments are in the making. Hopefully, with Israel on one end of the confrontation Turkey's threats will remain empty in much the same way that they remained empty immediately after the Flotilla event when Erdogan declared that he would board a Turkish warship and sail to Gaza himself (prompting a reply by some not so calm heads in Israel that "if he does, we'll sink it!
)
