While the best defense in many sports may be a good offense, an offense in war is not defensive, not when it generates hatred, resentment, and blowback, not when the alternative is no war at all. Through the course of the so-called global war on terrorism, terrorism has been on the rise. This was predictable and predicted. The wars on Iraq and Afghanistan, and the abuses of prisoners during them, became major recruiting tools for anti-U.S. terrorism. In 2006, U.S. intelligence agencies produced a National Intelligence Estimate that reached just that conclusion. Read More.
War's weapons risk intentional or accidental apocalypse.
We can either eliminate all nuclear weapons or we can watch them proliferate. There's no middle way. We can either have no nuclear weapons states, or we can have many. As long as some states have nuclear weapons others will desire them, and the more that have them the more easily they will spread to others still. If nuclear weapons continue to exist, there will very likely be a nuclear catastrophe, and the more the weapons have proliferated, the sooner it will come. Hundreds of incidents have nearly destroyed our world through accident, confusion, misunderstanding, and extremely irrational machismo. And possessing nuclear weapons does absolutely nothing to keep us safe, so that there is really no trade-off involved in eliminating them. They do not deter terrorist attacks by non-state actors in any way. Nor do they add an iota to a military's ability to deter nations from attacking, given the United States' ability to destroy anything anywhere at any time with non-nuclear weapons. The United States, the Soviet Union, the United Kingdom, France, and China have all lost wars against non-nuclear powers while possessing nukes.
Oil can be leaked or burned off, as in the Gulf War, but primarily it is put to use in all kinds of machines polluting the earth's atmosphere, placing us all at risk. Some associate the consumption of oil with the supposed glory and heroism of war, so that renewable energies that do not risk global catastrophe are viewed as cowardly and unpatriotic ways to fuel our machines.
The interplay of war with oil goes beyond that, however. The wars themselves, whether or not fought for oil, consume huge quantities of it. The world's top consumer of oil, in fact, is the U.S. military. Not only do we fight wars in areas of the globe that happen to be rich in oil; we also burn more oil fighting those wars than we do in any other activity. Author Ted Rall writes:
"The U.S. Department of [War] is the world's worst polluter, belching, dumping, and spilling more pesticides, defoliants, solvents, petroleum, lead, mercury, and depleted uranium than the five biggest American chemical corporations combined. According to Steve Kretzmann, director of Oil Change International, 60 percent of the world's carbon dioxide emissions between 2003 and 2007 originated in U.S.-occupied Iraq, due to the enormous amount of oil and gas required to maintain hundreds of thousands of American military forces and private contractors, not to mention the toxins released by fighter jets, drone planes, and the missiles and other ordnance they fire at Iraqis."
The U.S. military burns through about 340,000 barrels of oil each day. If the Pentagon were a country, it would rank 38th out of 196 in oil consumption.
The environment as we know it will not survive nuclear war. It also may not survive "conventional" war, understood to mean the sorts of wars now waged. Intense damage has already been done by wars and by the research, testing, and production done in preparation for wars.
Wars in recent years have rendered large areas uninhabitable and generated tens of millions of refugees. War "rivals infectious disease as a global cause of morbidity and mortality," according to Jennifer Leaning of Harvard Medical School.
Perhaps the most deadly weapons left behind by wars are land mines and cluster bombs. Tens of millions of them are estimated to be lying around on the earth, oblivious to any announcements that peace has been declared. Most of their victims are civilians, a large percentage of them children.
The Soviet and U.S. occupations of Afghanistan have destroyed or damaged thousands of villages and sources of water. The Taliban has illegally traded timber to Pakistan, resulting in significant deforestation. U.S. bombs and refugees in need of firewood have added to the damage. Afghanistan's forests are almost gone. Most of the migratory birds that used to pass through Afghanistan no longer do so. Its air and water have been poisoned with explosives and rocket propellants.
If militaries were made green in terms of their operations, they would lose one of their main reasons for war. (Nobody can own the sun or the wind.) And we would still have a long list of ... More reasons to end war.
