They have been integral part of the NATO military alliance that bombed Yugoslavia, Afghanistan, Iraq, Libya and Syria, lending military bases and participating in missions. Hardly solving through "peaceful means". It is just that they are on the "right side".
The bombing campaign of former Yugoslavia lasted for 10 weeks and stopped a series of civil wars that had gone on for 10 years and claimed at least 130 000 lives. The whole campaign killed a few hundred people, less than were executed in a few days in some of the worst massacres there, and brought peace that has lasted for 25 years and counting. So indeed they were on the right side.
