This is what we expect from Americans though. They decry the loss of American lives, even when those specific persons were involved in murdering people who aren’t and don’t want to be American.

You’ll notice that people from other places don’t talk that way. Europeans don’t talk about “French lives,” Japanese don’t talk about “Japanese lives,” and Iranians don’t talk about “Iranian lives.” It’s a uniquely American thing and it’s all about an ingrained sense of American exceptionalism.
