That statement should more accurately target "US allies". The US is at the top of the system and can largely do whatever it wants, no one's going to slap sanctions on us over landmines. However our (western allies) strength gives our allies the confidence they need to voluntarily give them up, and we can coerce other nations to give them up to be part of our club. It's all a power play at the end of the day, the ethical argument is window dressing. Some people take window dressing very seriously, but don't mistake that for being the decisive factor in policy.
