Perpetual War or Search for Peace?

Is US fighting force big enough?

American's armed forces are growing bigger to reduce the strains from seven years of war, but if the US is confronting an era of "persistent conflict," as some experts believe, it will need an even bigger military.
A larger military could more easily conduct military and nation-building operations around the world. But whether the American public has the appetite to pursue and pay for such a foreign-policy agenda, especially after more than five years of an unpopular war in Iraq, is far from clear.
Last week, the Army released a new manual on "stability operations" that outlines for the Army a prominent global role as a nation-builder. The service will maintain its ability to fight conventional land wars, but the manual's release signals that it expects future conflicts to look more like Iraq or Afghanistan than World War II. While Defense Secretary Robert Gates has not publicly supported expanding the force beyond what is already planned, he has said the United States must prepare for more counterinsurgency wars like the ones it is fighting now – a hint that a larger military may be necessary.

As stated before - time to shift our thinking. Why must it be perpetual war? Why must our "face" in foreign nations be behind a gun? Isn't it time for diplomacy? Isn't it a time to shift our focus? Haven't we learned from our mistakes in Iraq and Afghanistan and every other conflict we have been involved in?
