Sweden once ran a chunk of the USSR, I didn't specify their overseas colonies. The Danish empire gives them claims to things (like Arctic resources) into the modern age. Each was a significant part of the history of each nation. Heck still is, hello Greenland.
You act like I can't search Wikipedia. All those other nations you mention rode the imperialist world to the end and paid a price for that in destructive wars and the costly aid that was required by a modern sensibilities. That was my point- Switzerland, Belgium, Denmark and Sweden are the Mark Cuban's of the European world. They got in and out when it was good to do so, just like Mark sold before the dot com bust.
Therefore Denmark, like Mark, is an exception and not a rule.
Just like America would be an exception in the same discussion. Unlike the rest we are the ones that have to spend the money needed on the military force the world needs to run smoothly. Every modern European power has skirted that responsibility so much recently all of their social programs basically have an American subsidy by default. I hope Putin forces them to chip in more soon, France and Britain splitting an air craft carrier is embarrassing.
So you're not talking ancient history, but ancient, ancient history, right?
And you're not very good at Wiki, otherwise you'd know that Switzerland never was colonialist. Like I offered, you began with mistaken belief & now stre-e-e-tch whatever you can find to justify it. The same applies to your take on Greenland. Norse colonies in southeastern Greenland predate Eskimoes in that area. In the euro-centric world view, nobody else ever claimed the place, so Danish claims held even when there were no European inhabitants.
Perhaps you should start again, set faith aside & examine reality before forming opinions.
Our military might is an interesting study in contradiction. It's big gubmint like nothing else can be, in case you hadn't noticed. And while we have been a stabilizing force in different times & places, that's not true of recent Neocon adventures at all.
None of that has much of anything to do with the subject, anyway.
There are 3 centers of power in the human political realm- Organized Religion, Wealth, and the upstart, Democracy. Our govt is an expression of all 3 and the only expression of democracy, so when we tear it down we just make room for the other two to encroach on the power of the People. Which is, for sure, the rationale of Oligarchical conservative leadership in this country, at least when they're out of power. When in power, their govt serves the interests of wealth better than any other.
