An Unexploded Ordnance From Ww2

On Christmas Day in 2016, 54,000 Augsburg residents had to be evacuated from their homes while explosives experts worked to defuse a RAF b**b from WWII found under a construction site. If detonated, the 2-ton b**b could have destroyed all buildings within a mile radius. The unexploded b**b was one of many discovered in Europe and Asia multiple years earlier.
I'm wondering, if s/o writes:
"Faaaake - how can it be?
The US exist since 1776-07-04 ! Nothing can be before!
Don't be a woke leftist, do your own research, touch some grass and never trust science or the universities!"
Bomb! What the fuck?
