High-tech warfare and the Iraq War 2003

From the Atomic Bomb to Deterrence

The use of atomic bombs on Hiroshima and Nagasaki in August 1945 ended the Second World War and reshaped the rules of military planning. By 1952 Britain had its own atomic weapon; by 1957, a hydrogen bomb. The strategy that grew up around these weapons was nuclear deterrence — the idea that no enemy would launch a first strike if the response would destroy them too. The doctrine of mutually assured destruction (MAD) shaped British procurement decisions: the V-bomber force in the 1950s, the Polaris submarine fleet in 1968, and Trident from 1994. The 1957 Defence White Paper by Duncan Sandys explicitly traded mass conscription for the nuclear umbrella, opening the way to the all-volunteer army.

Key Fact

Nuclear deterrence (Britain’s atomic bomb 1952, hydrogen bomb 1957, Polaris 1968, Trident 1994) shifted spending from mass conventional forces to small, technical, professional services and ended National Service in 1960.

Computerised Weapons

The second great twentieth-century shift was the computer. Radar, code-breaking machines and early ballistic computers were developed in the Second World War, but it was the silicon revolution from the 1970s onwards that produced the precision-guided munition. The 1991 Gulf War, in which Britain participated as part of the US-led coalition, was the first conflict shown live on television with cruise missiles and laser-guided bombs hitting buildings on camera. Cost-per-target collapsed; civilian casualties from inaccurate area bombing fell relative to earlier wars; the moral and political pressure on commanders to use precision weapons rose accordingly.

ISTAR: Seeing the Battlefield

Computerised warfare is as much about seeing as about hitting. ISTAR systems integrate satellite imagery, signals intercepts, radar tracks and unmanned aircraft into a single real-time picture for commanders. Britain’s Watchkeeper drone, Sentinel surveillance aircraft and the GCHQ signals organisation contribute to this picture. The unmanned air vehicle, or drone, can loiter over a target for many hours and strike with a Hellfire missile from beyond visible range — a capability that did not exist in mass form until after 2001.

It is tempting to treat computerised warfare as a clean break from the past. The longbow at Agincourt, the rifled musket of the Crimea and the artillery of the Somme were all in their day ‘precision’ weapons compared with what came before. The novelty in the 1990s was not precision in itself but the speed of the targeting cycle: a digital camera in the air, a satellite link, a commander’s decision and a weapon released — all within minutes. The thread back to William Howard Russell’s telegraphed Crimea reports is the same compression of distance and time that mass communications produce.

The Iraq War 2003

Britain joined the US-led invasion of Iraq in March 2003 under Prime Minister Tony Blair. The official case rested on intelligence that Saddam Hussein’s Iraq possessed weapons of mass destruction; the Iraq Survey Group later concluded these stockpiles did not exist. The conventional invasion was short. A combined British and US force took Basra in early April after three weeks of fighting; Baghdad fell to US forces on 9 April. Air dominance came from US carriers and from RAF Tornado and Harrier squadrons; ground operations used the Challenger 2 main battle tank, GPS-guided artillery and Apache attack helicopters. The conventional phase was a textbook demonstration of high-tech warfare: small precision-armed professional forces overwhelmed a much larger but technologically inferior conscript army.

The Insurgency and the Limits of High-Tech

After Saddam fell, the war Britain had not planned for began. Sunni Arab and Shia militia groups launched a sustained asymmetric warfare campaign against coalition troops, using improvised explosive devices (IEDs) along main supply routes, sniper attacks, mortar fire on bases, and suicide bombings of Iraqi police and civilians. British forces in Basra Province were drawn into a six-year counter-insurgency campaign. Precision weapons could destroy a confirmed target, but they could not identify which civilians in a Basra street were Mahdi Army and which were not. ISTAR could see a roadside ditch, but it could not tell which ditch contained an IED. The limits of computerised, precision-led warfare against a determined low-tech enemy — familiar from the American experience in Vietnam — reasserted themselves.

The invasion succeeded because British and American forces had near-total air dominance, GPS-guided artillery, satellite and drone reconnaissance, encrypted communications and a professional, well-trained volunteer force. The occupation failed because high-tech tools were poorly suited to street-level intelligence work in Arabic, because the de-Baathification of the Iraqi army threw 400,000 trained men onto the streets, and because political reconstruction had been planned with optimism rather than rigour. The Chilcot Report (2016) concluded that British post-invasion planning was ‘wholly inadequate’.

War, Public Opinion and the Embedded Press

The Iraq War was the most televised British conflict to date. Embedded reporters travelled with British units; satellite phones produced live broadcasts from forward bases; an enormous February 2003 anti-war march in London brought roughly a million people onto the streets before the invasion began. Public mistrust of intelligence-led justifications for war — once Saddam’s WMD did not appear — produced a long shadow on British politics. By the late 2000s any government proposing a similar deployment faced a much more sceptical electorate, demonstrated when the House of Commons in 2013 refused to authorise British strikes on Syria.
