"many countries have joined a treaty banning landmines"

The ones that should join that treaty have not.

My country should not have joined. I'm from Finland. All that treaty ever did was to get rid of foot mines that we're designed to be planted around a heavy tank mine to make the whole deal difficult to disassemble. Now as our mines are easily disassembled, it just kind makes attacking here easier. So completely opposite outcome is very probable than what was intended.
