The parties in the Greek coalition government have undertaken a huge task and burden, and they seem to be doing a relatively good job of it so far.
They have succeeded in keeping the debt-wracked country in the eurozone and have managed to hold together for a significant time a collaboration that is unprecedented in the governance of this country.
No one expects these three incongruous parties to agree on everything given the vast differences in their philosophies and fundamental policies.
They do, however, need to set some rules regarding how they deal with their various differences when these arise.
The Greek political system is in a very tenuous position right now and it would take very little for the balance to be lost and the situation to get out of hand.
One faux pas or one wrong word could prove catastrophic, not just for the parties themselves, but for the country as a whole as well.
