A lot of people are terrified of landmines. That's why there are treaties around the use of landmines, such as the Ottawa Treaty [0], which ban anti-personnel landmines. 164 countries have signed that treaty.
I don't like this "whataboutism".
In addition, while landmines are terrifying and deadly, they stay in one place. People generally don't need to fear them when going about their day. Drones on the other hand are mobile, they could fly into a city and kill people. They could fly on your property and kill you.
