There are different forms of government. That is obvious. Some are better than others. In the case of representative democracy it depends on whether the people running it are honest. Others depend on one man to get it right. It works - sometimes.
The Wiki tells us that a republic is a country which is not, in theory or practice owned by its rulers. That lets England out, America ditto. They are both run as Zionist Occupation Governments [ ZOG ] using corrupt politicians who are bribed, blackmailed or just plain power crazed.
Republics can be good. It all depends on who is pulling the strings.
