The wt mindset is anchored in the downward spiral of mankind since Eve's perfection. and of course that negates the astonishing improvements in humans and their accomplishments. It is kind of a fatalism. and then the constant thwarting of human advancement by "god": the flood, the tower of babel, and then Satan's world rule. Only service and contribution to wt will cure all that. "angst" to the german mind might not be the right word, it means fear. It is more of a pessimism, fatalism channeled into useless non self improvement, aka religion. a good thing to be aware of cofty. thanks.
There can of course, be real cause for "welt angst" if condition take an uncontrollable turn south, new "leaders", new weapons.
