In brief, the Global War on Terror sledgehammer strategy has spread jihadi terror from a tiny corner of Afghanistan to much of the world, from Africa through the Levant and South Asia to Southeast Asia. It has also incited attacks in Europe and the United States. The invasion of Iraq made a substantial contribution to this process, much as intelligence agencies had predicted. Terrorism specialists Peter Bergen and Paul Cruickshank estimate that the Iraq War “generated a stunning sevenfold increase in the yearly rate of fatal jihadist attacks, amounting to literally hundreds of additional terrorist attacks and thousands of civilian lives lost; even when terrorism in Iraq and Afghanistan is excluded, fatal attacks in the rest of the world have increased by more than one-third.” Other exercises have been similarly productive.

A group of major human rights organizations—Physicians for Social Responsibility (U.S.), Physicians for Global Survival (Canada), and International Physicians for the Prevention of Nuclear War (Germany)—conducted a study that sought "to provide as realistic an estimate as possible of the total body count in the three main war zones [Iraq, Afghanistan, and Pakistan] during 12 years of ‘war on terrorism,'" including an extensive review “of the major studies and data published on the numbers of victims in these countries,” along with additional information on military actions. Their "conservative estimate" is that these wars killed about 1.3 million people, a toll that "could also be in excess of 2 million." A database search by independent researcher David Peterson in the days following the publication of the report found virtually no mention of it. Who cares?

More generally, studies carried out by the Oslo Peace Research Institute show that two-thirds of the region’s conflict fatalities were produced in originally internal disputes where outsiders imposed their solutions. In such conflicts, 98 percent of fatalities were produced only after outsiders had entered the domestic dispute with their military might. In Syria, the number of direct conflict fatalities more than tripled after the West initiated air strikes against the self-declared Islamic State and the CIA started its indirect military interference in the war—interference which appears to have drawn the Russians in as advanced US antitank missiles were decimating the forces of their ally Bashar al-Assad. Early indications are that Russian bombing is having the usual consequences.

The evidence reviewed by political scientist Timo Kivimäki indicates that the “protection wars [fought by ‘coalitions of the willing’] have become the main source of violence in the world, occasionally contributing over 50 percent of total conflict fatalities.” Furthermore, in many of these cases, including Syria, as he reviews, there were opportunities for diplomatic settlement that were ignored. That has also been true in other horrific situations, including the Balkans in the early 1990s, the first Gulf War, and of course the Indochina wars, the worst crime since World War II. In the case of Iraq the question does not even arise. There surely are some lessons here
