The US has done many horrible things, but that's an awful list to go by. It mixes US involvement in the Philippines and the nightmare that was with "Israel killed someone and it's likely the US was aware", NATO involvement in Bosnia, and the US usage of radio and press releases to influence world opinion in its favor.
Specific incidents in Bosnia? Certainly. But on the face of it, the US joining with other nations to intervene in an ethnically driven civil war isn't an attrocity. The US being aware of an Israeli operation isn't a US attrocity. Propaganda isn't an attrocity.
Hell, one entry literally seemed to be "American soldiers reported a South Korean war crime through appropriate channels, and this didn't change US foreign policy"

Mixing actual attrocities in with the benign or unrelated things just dilutes the actual attrocities, particularly when the preamble says to play up to emotional outrage.
