Just remember, reflexive skepticism about Western military action is by its very nature fallacious. Every situation must be evaluated on its specific merits. How can we know in advance that army units will model themselves into Kill Teams and go around massacring villages? This is not to say that once we have invaded and occupied a foreign nation and our army units have modelled themselves into Kill Teams and gone around massacring villages we should approve. Indeed, having invaded and occupied a foreign country and then beset their countryside with Kill Teams, we should strongly disapprove of Kill Teams. But to presume in advance that these Kill Teams will exist based simply on the precedent of every major conflict in the last six decades is to engage in logically fallacious a priori reasoning. The only moral moral objection to armed massacres is retrospective.
