The disappearance, and possible murder, of Jamal Khashoggi, a high-profile critic of the Saudi regime, is the latest, disturbing addition to the rising toll of state-directed, extra-territorial kidnappings, abductions and killings around the world. So here's the question: why do more and more governments think they can get away with murder, figuratively if not literally? It's a problem that should concern everybody - because everybody is at risk. It's tempting to blame the US, a country that ... has come to epitomise the problem. In January 1986, worried about American hostages in Lebanon, Ronald Reagan signed a top-secret covert action directive. The presidential finding" authorized the CIA to kidnap suspected terrorists anywhere, any place. Reagan's "snatch and grab" operations inaugurated the modern-day practice of state abduction, leading ineluctably to extraordinary rendition. They set a fateful precedent. George W Bush massively expanded rendition after the 2001 terror attacks. Although the UN classifies one country's abduction of another country's citizens as a crime against humanity ... the US and its accomplices have in practice faced no substantive sanction or penalty to date. This grim lesson in impunity has been absorbed and digested by governments everywhere. The Khashoggi disappearance, almost certainly ordered and planned in Riyadh, is the very sort of illegal action that has been normalised ... by very recent American practice from Afghanistan and Iraq to Libya and Cuba.
