As an American, I sometimes get demoralized at the degree of brainwashing in our public schools, media, etc. It has a very detrimental impact on the ability of our population to think flexibly and critically.
I do want to thank many/most of the English-as-a-2nd-lang posters here for cheering me up about the sad state of _our_ systems and reminding me that things could be much worse. OTOH, it also means that we've got a lot further to sink yet which is a bit depressing.
People are seldom united when there is nothing to unite over. Unity comes from a big threat that threatens them all.
At the time of the formation of the U.S., the bigger threat was England and King George. Even when France united with the new USA to fight her age-old foe, England, she did it because of a common threat. Not because she truly believed in freedom the way it was being set in place in America.
France wasn't really an ally. It was only a temporary thing to put England in its place. In a similar (though smaller) way, the colonies in America were not united. This was proven out in the Civil War.
Regarding world freedom, it is gun freedom in America that is keeping the world free. How? Governments of the world realize how dangerous their people would be if they had guns. So, they don't antagonize their people too hard If they did, their people might go and get guns from America and depose their government. And, actually, this has happened over and over with countries around the world... the people get guns from America and fight their government to get American-type freedom.
The problem in America isn't the guns. The problem is the respect we all have for each other... even if we are of different races. This will change as more and more Muslims come over here and get guns. Why will it change? Because Islam doesn't allow Muslims to respect other people in the ways that other people might respect them and each other.
