So what's the middle ground between constitutionalism and Communism? There is none.. It's like trying to find middle ground between the Jews and Palestinians.
Don't mean to rain on your parade, but that is a really badly stated argument.
Communism does not at all define the political system.
So a country that allowed communist means of production, could be a democratic republic, monarchy, dictatorship, or whatever.
Political systems and economic systems are orthogonal. They have nothing to do with each other.
As for the Jews and Palestinians, the Palestinians are Semitic, and are the descendants of the ancient Canaanites, Akkadians, Urites, Chaldeans, Hebrew, Amorites, etc.
The Jews are not some different group, but a small number of the Palestinian Hebrew, who left for thousands of years, and now have returned.
There is no reason for any sort of conflict at all, except that the Jews have filled themselves with some sort of insanity about them being the "Chosen People" who are supposed to be due their "Promised Land", and they want the Palestinians to deliver on this fake biblical promise.
There is plenty of "middle ground".
All Jews have to do in order to avoid conflict, is to buy property instead of stealing it with massive US weapons.
There is always middle ground.
But what we have to do is explain to some who are unfamiliar with firearms, that no firearm ever caused anyone to ever do anything, like commit a crime.
We know the causes of crime, and the ease of weapons acquisition is not one of them.
