i dont know if you're from europe or not. if you are from europe, you should know better than to make that claim. we are not even close to finishing the cleaning up of UXO from the wars.

Experts reckon it could take another 500 years to clean up the mess... ...Even today (in Germany), more than 2,000 tonnes of unexploded munitions are dug up annually and all construction sites need to be certified as cleared of unexploded ordnance (UXO).

i do get where you're coming from with your first statement, it's just... maybe a bit strongly worded, and definitely, factually incorrect. bosnia is a prime example of a white country that is absolutely littered with UXO and mines. i'm not trying to downplay the severity of the UXO issue in southeast asia, just to make the point that white countries don't have some magic intrinsic ability to clear mines faster.

i cant be bothered to research anymore, so i will guess that the UXO clearance rate is mostly a factor of time, and mostly a factor of the amount of initial UXO that was deployed. if anyone wants to follow up on that (because i'm lazy) then go ahead 😃
