The yellow question mark, mocking the yellow ribbon, has the following on it:
Question War.

I don't quite know how to respond to that question due to the necessity of war.
War is the equivalent of the second amendment to the U.S. Constitution for nation-states. Just as every person has the right to defend himself, so does every nation have the right to defend itself, and its citizens.

I question the mental stability, as well as the worldview that holds such a question as pertinent. One may question a war but not war itself.
As long as there are evil people, war will be required. Remove evil people, and there will be no war. Good Luck on not using war to get rid of them or the ideas that drive such people.

I have tried to engage such people in debate, and they always, always descend into name-calling and personal attacks. It is a sort of casting pearls thing I suppose.
