But I do believe we should do everything in our power short of direct intervention to discourage acts of overt aggression against sovereign nations.
We all know how quickly things can get out of hand if there is not a reason for aggressive nations to think twice.
You mean like bombing Serbia?
It worked in Japan and Germany, but not much of anywhere else. But then, we made sure the enemy was totally defeated before even trying to make nice which we have not done since then.
