its Fundamental Government has a large support from the poplulation and there is no real opposition?
I don't think the situation there is that simple. There is real opposition - it's jailed and/or executed.

What popularity poll should we use to determine if a government is supported by the populace? Is 50% a high enough level of support? 75%?

How can we tell if "the people... understand or appreciate their freedom"?

Does the US understand or appreciate our freedom? I would argue no.
