The tragic fate of those aboard Malaysia Airlines Flight 17, apparently downed by a surface-to-air missile, has sparked global public sympathy for the victims and condemnation for those responsible.
Our best hope of containing this threat to air travel is to act quickly by tightening international covenants on access to weaponry that takes down aircraft.
The source of the missile and launcher that downed Flight 17 appears to be Russian but there are other potential sources for would-be copycats. The sources for the Hamas rockets against Israel likely include Iran, Pakistan and China. The arsenal of the new caliphate, declared by the Sunni-led rebellion against the Iraqi government, now includes captured weapons made in the United States.
Since Cain and Abel too many still subscribe to the quip by the amoral arms merchant, Undershaft, in George Bernard Shaw's Major Barbara, that "Nothing is ever done in this world until men are prepared to kill one another if it is not done."
The arms industry is big business. Given human nature, it's also a necessary business.
The Stockholm International Peace Institute (SIPRI) estimates the global arms trade to be worth at least $43-billion (U.S.) and likely much higher because many states, notably China, do not release data on arms exports.
Canada's Foreign Affairs Department reports that our exports of military goods and technology are worth $635-million (Canadian). Most of it goes to fellow NATO allies, but also to countries including Afghanistan, Egypt, Ukraine and Yemen.
Like most countries, we have in place elaborate export controls and safeguard agreements to ensure our weapons are "not prejudicial to peace, security or stability." We don't export to nations on the UN sanctions list or those with "a persistent record of serious violations of the human rights." All goods destined for North Korea or Belarus require a permit.
Even then, no system is fail-safe.
India developed their nuclear weapons capacity in 1974, sourcing from CANDU reactors. It chilled Indo-Canadian relations for decades until Prime Minister Stephen Harper concluded a nuclear co-operation agreement in 2013 under safeguards applied by the International Atomic Energy Agency (IAEA).
In the arms bazaar, nuclear proliferation is the greatest danger.
Like his predecessors, President Barack Obama, is working to contain proliferation through negotiation, sanctions and international law. Slow and frustrating, there is discernible progress.
Notwithstanding current tensions, Russia and the United States completed a new nuclear arms treaty (START) in 2011, setting out new limits on intercontinental ballistic missiles and nuclear warheads.
Sanctions have brought Iran to the bargaining table in Geneva. U.S. Secretary of State John Kerry has concluded there is sufficient "tangible progress" to extend discussions beyond the July 20 deadline.
North Korea remains a problem, still firing missiles and rockets, despite continuing condemnation from the UN Security Council.
A series of international nuclear security summits – Washington, Seoul, the Hague – were initiated by Mr. Obama in 2010.
They have resulted in minimizing the use of highly enriched uranium, higher security standards at nuclear facilities and measures to detect and prevent the illicit trade in nuclear materials.
Canada has pledged funds to help non-proliferation efforts, ratified international covenants on suppression of nuclear terrorism and protection of nuclear materials.
There are similar efforts to curb and control conventional weapons, like that which brought down Flight 17.
The United Nations Register of Conventional Arms, to which Canada was a founding contributor, obliges governments to voluntarily supply data on their imports and exports. Seventy nations, including Canada, have done so consistently.
The Wassenaar arrangement of 41 states, including Canada, aims at preventing transfers of conventional weapons or dual-use goods to illegitimate end-users.
As with nuclear non-proliferation, containing conventional weapons remains a work-in-progress.
Concerted international action, abetted by technology that improves detection and attribution, can work "to save succeeding generations from the scourge of war," the UN Charter says.
Chemical weapons killed and blinded tens of thousands during the First World War. Popular revulsion led to the Geneva Protocols proclaiming that "the use in war of asphyxiating, poisonous or other gases … has been justly condemned by the general opinion of the civilized world."
The prohibition against chemical weapons endures. When breached – most recently by the regime of Bashar al-Assad in Syria – there has been sanction and remedial action.
Every day, an estimated 5.4 million people board airplanes. By midday, air traffic over Canada and the United States alone reaches an estimated peak of 5,300 flights.
Confidence in global aviation safety obliges action by the international community. Air travel is difficult enough without worrying about missiles.
