Yes and no. Yes insofar as a majority of the Western (United States and EU to a lesser degree) military actions post-Cold War have been for humanitarian reasons; Kosovo, Somalia, original Iraq war, etc. We (the West) sent troops into the situation not because our national interests were threatened, but because some brutal dictator / warlord / whatever was committing genocide / murdering all his people / etc. And we (again, the West) thought this was wrong. So there is a moral component here.

However, these military actions represent a small fraction of the wars going on around the world, most of which are internal civil conflict; Chad, Nigeria, ethnic conflict and insurgency in India, etc. Not really much of a moral component in these conflicts.
