Basically, yeah, different definitions. But destroyed means to end the existence of, generally by attacking. The Euro very much still exists, so I think I'm using the term more correctly when I say the dollar has not destroyed the Euro. You can pick a date and get a drop like 37%. Or you could pick a different date and the Euro is up against the dollar today from that other date (yeah you would have to pick an all time low like back in 2001). Down 20% in a year is a major drop. I've never even remotely done FOREX trading, so I can only guess what moves like this mean to them.
There is a major war going on in Europe. Does not surprise me that the Euro is down. It is probably temporary because the Euro is not destroyed.
