I suppose you should rather ask the question, when is the last time I haven't been in Europe, since I live on the continent. As for which countries I've visited, Germany, France, Sweden, Norway, Netherlands, etc. The usual suspects. But I don't see how that matters at all as far as my point is concerned, generally speaking.
I don't need to be in a boxing ring to say that the business is generally down from what it used to be. I do not even need to be an accomplished historian to know that Europe has not played much of a part in shaping the world, nor has it taken control of its destiny since 1945. It merely reacts and adapts to circumstances outside of its own control. But does it have any control over world events, comparable to a United States? No. Does its word have any weight, for example, to prevent a situation like the one in Crimea and Ukraine from happening? Nope. Its word carries approximately zero weight since it cannot be backed up by action, considering that many European countries do not even have standing armies, and are fully dependent on America providing security and stability.
Since the Cold War, Europe has been squeezed in between the Eastern and the "real" Western interests (America), and the collapse of one piece of shit communist structure in USSR did little to increase its importance, as another production monster has now risen in China, encouraging the merchants to abandon Europe to rot, in order to take financial advantage of the massive slave market in Asia, which fully understands and is itself actively taking advantage of the weakness of the "capitalist free market" ideal, where money holds more value than principles. The Chinese will not compromise their own, but they will make sure the the others will, now that they are in a position of power.
Eastern Europeans are very much different from Western Europeans.
Subconsciously most people do understand. But I suppose it is too painful to admit that we are not as our ancestors were. We are merely replaceable cogs who play a very limited role within the "machine", with all the individual worth of an ant, who unlike such insects, have been separated from the idea of having anything common with his fellow man, who have no real common objective to work towards under the "multi-cultural" environment, as one man wishes for Sharia law while the other for a "safe space". Without individual worth, and without a collective ideal to live for, it is no surprise that the European man has fallen so low.
Who would rise up in arms to defend Europe and its values, as the men of the past may have, to defend their own? Nobody. No one would die over European "ideals", because they truthfully mean nothing to them, despite all the behaviouristic conditioning from birth, to make one a "European citizen" rather than one of his native country. Europe and what it stands for, means nothing.
If Genghis Khan or Hannibal showed up in the modern day, the Europeans would open the gates. Well, I suppose, in a way they already have, considering how many military-aged males from an active jihadist war zone were admitted into the EU.
