From 1946 through 1958, the US detonated 67 nuclear weapons in the Marshall Islands, with an explosive force equal to 1.6 Hiroshima bombs every day for 10 years. The Marshallese are still dealing with the consequences to this day.
Lingering radiation has caused numerous health problems and wiped out much of the traditional lifestyle of fishing and farming, leading to a dependence on unhealthy imported food and an epidemic of obesity and diabetes. Many Marshallese emigrated to America, where maintaining traditional culture was even more difficult.
The health challenges from their lifestyle changes led to American Marshallese being tragically vulnerable to the Covid epidemic.
