The US Dollar Index was at 120 in early 2002, and then proceeded to fall persistently until the middle of 2008 when it rested at around 71. An epic collapse by the dollar that triggered all sorts of nasty global effects. Fortunately this time around the dollar drop hasn't been so bad, most major currencies are debasing at the same time. The dollar is merely back to where it was in 2015 and 2018, so far.
