Europe doesn’t need any help. It’s well on its way to self destruction!
Western Europe in particular and, to be totally candid, it's just what they (the Western Europeans) have coming to them. They had "Catholic" Nations for centuries and deliberately "threw away" their unifying faith and a large part of their cultural identity. Even the "Protestant" Western European nations threw away their centuries-old yet erroneous Christian culture. At least the U.S. never deliberately threw away any "national unity of faith" since it never had any in the first place.
Western Europe is also very spoiled and extremely naive whem it comes to directly experiencing the horrors of any fierce and directly open Marxist/Communist nations that the Eastern Europeans directly experienced for decades following WW2 when the " Allies" (ALL LIES) deliberately handed over Eastern Europe to it's Soviet ally (and then pretended that the Soviets - all of a sudden - had become "our biggest enemy" when the truth is that the U.S. and it's Euro Allies had ALWAYS supported "Communism" and Communist nations, both overtly and covertly...but that's a whole other story).
The U.S. is no different than the Western European nations when it comes to living this spoiled and naive existence. Although, I am very thankful I am in the U.S. rather than in Western Europe for many reasons.
Personally, I never had any desire to visit Europe (Western Europe especially) since they threw away most of their culture and customs in favor of U.S.-created and exported "Modern Western Culture" like T.G.I.Fridays in Germany, Pizza Hut in Egypt (I know that's not Europe but still), smartphones and shirts with American-created companies on them everywhere you look.
Why travel thousands of miles to see the same stuff I can see a mile away from my own home? That's what happens to those who travel to Western Europe today.
