There are more effective tools than war for protection.
In arming, many factors must be considered: weapon-related accidents, malicious testing on human beings, theft, sales to allies who become enemies, and the distraction from efforts to reduce the causes of terrorism and war must all be taken into account. So, of course, must the tendency to use weapons once you have them. And a nation’s stockpiling of weapons for war puts pressure on other nations to do the same. Even a nation that intends to fight only in defense, may understand “defense” to be the ability to retaliate against other nations. This makes it necessary to create the weaponry and strategies for aggressive war. When you put a lot of people to work planning something, when that project is in fact your largest public investment and proudest cause, it can be difficult to keep those people from finding opportunities to execute their plans.

War making provokes danger.
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.
