More fitting examples would be the USS Stark or USS Liberty. I'm not happy when anyone dies who doesn't want to kill others. Putin wants to kill others. You simply can't look at the pictures of distroyed homes and dead people across Ukraine and come to any other conclusion. Whether that killing is justified is left for each person to decide.

For example, do I believe the U.S. was justified in killing Iraqis in the 2nd war. No. There are many actions I don't feel justified. Bottom line, I'm not happy about the Thresher OR the the Kirsk.
