The military conflict has some interesting points to ponder.
Seeing the situation from the point of view of the commanders of each side provides some challenges.
The National Guard has a comparatively limited objective, to recapture the north. The area is right next door, so there is no major logistical problem. The biggest problem the NG would face is preventing the air force and navy from operating, which is doable but not with current military thinking.
Inventive thinking would require preparations to deal with HARM and HOPPY weapons that the Turkish air force has, and so far there is not much preparation in that direction.
In the event of a defensive action, the NG will have the task of dealing with 400 tanks in addition to the air force and navy. Again, it is doable, on the same conditions as above. There are weapons in the arsenal of the NG right now that can deal with tanks very effectively.
Looking at the situation from the other side, in the case of a defensive action they would have to call in air support and possibly naval bombardment of coastal areas. The question here would be to bomb what? During the first minutes of a military action there is dispersal of forces and all bases are empty and basically useless as targets. Bombing ports and civilian targets would not offer much support to the military.
In an offensive action presumably the objectives would be to capture key poins such as ports, air ports, communications and to blockade the island, cutting off the seaway between Greece and Cyprus.
The actual situation on the ground would quickly become secondary to the international political situation that would arise. Whoever is the attacker, or is seen to be the attacker, would be quickly slapped down by powers that value stability. It is unlikely that any projection of power in international waters would be tolerated for long. Neither could the conflict be kept localised for more than a day or two before it escalates to a full confrontation between Greece and Turkey on a front stretching from Cyprus to the triple border point with Bulgaria. Whatever happens must happen in hours rather than days.
Suppose one side prevails, and takes over the whole island, then comes the problem of "now you got it, what are you going to do with it". Which of the two sides has the means to police hundreds of thousands of armed people who will be taking pot shots at the enemy?
Definitely not an easy one.
