Idealism is beautiful, but impractical. There is no such thing as a global peace based in the goodwill of governments worldwide, nor there is a chance for global de-militarisation. The Roman Empire was strong until their military decayed (for whatever reasons). Then they got their asses kicked for good, and the Dark Ages followed. I'd rather not have that happen again, thank-you-very-much.
