I mean... The war is extremely illegal and is being carried out at the direction of some of the most evil people alive. But I don't think "cowardly" fits here. If you are at war (ignoring the legality and morality of the war itself) and your enemy publicly reveals a location of one of their military assets, at a time and place where you know it will be defenseless and entirely devoid of civilians, is it really "cowardly" to attack it? If it's "cowardly" because it was an ambush attack, may I remind you that essentially all warfare over the last century has been composed almost entirely of ambush attacks?

Again, the war itself is disgusting. People should be publicly hanged for this. But I really don't see how the word "cowardly" fits into this particular attack.
