The Trump administration is expected to soon announce new government-backed strategies for boosting US weapons sales, according to news reports.

The policy change would downplay human rights considerations, and the murderous impact of the weapons trade, and give more consideration to the potential benefits to American jobs, and manufacturers of machine guns, fighter jets and drones. Staff at US embassies around the world would even be tasked with keeping tabs on military tenders and briefing visiting US officials

Already, foreign weapons sales have been increasing under President Trump, rising to $42 billion in 2017, from $31 billion in 2016, according to the US Defense Security Cooperation Agency, increasing the profits and stock market values of companies like Lockheed Martin, Boeing, Raytheon, General Dynamic Corp, and Northrop Grumman.

Behind all this spending is the appetite of governments, militia groups and private citizens, especially in the Middle East, to defend themselves in an unstable and dangerous world. An estimated 2.3 million people have been killed in armed conflict since the Cold War. That violence has an estimated economic impact of over $10 trillion a year, or 10% of the total global economy.

International efforts to regulate the global weapons trade have been mostly fruitless. The US, like Russia and China, have not yet signed and ratified the 2014 United Nations-backed Arms Trade Treaty.

An analysis of reported customs data from IHS’ Global Trade Atlas suggests that weapons trade is increasing – singularly difficult to evaluate.

Other surveys suggest that’s just a small part of what’s actually being shipped on boats and airplanes around the world. Annual arms purchases are estimated at somewhere in the neighborhood of $1.7 trillion a year, according to the Stockholm International Peace Research Institute. The hundred biggest companies in the world have sold over $5 trillion worth of weapons since 2002. When it comes to legally-registered weapons trade, the US is the world’s top exporter.

These numbers should be seen as a representative sample, instead of a complete picture. Global arms trade is cloudy. A Transparency International study estimated that trade in weapons accounts for around 40% of all the corruption in global trade.

Many arms deals come with tariff deals that exempt them from regular customs inspection. Some countries don’t include them in published customs data. Arms are often smuggled across borders. Weapons can be transshipped through a third country, or counted as something else. A tank, for example, might get shipped as a truck. Finally, because politicians often mandate that their defense departments buy weapons from manufacturers in their home country, contractors often figure out ways of importing parts, including many that are almost-made and require minimal transformation, but don’t get counted as weapons imports.

The main category of weapons that the US exports, and reports via its customs agencies, is bombs.

Three Arab countries are the US’s biggest customers, led by Saudi Arabia, which this past summer signed an arms deal worth a reported $350 billion over 10 years, including $110 billion in immediate sales.

The US is also the world’s biggest importer of customs-reported weapons, thanks in large part to civilians buying revolvers from Austria and shotguns from Italy.

For business analysts, and shipping and logistics companies, the traffic in guns, ammunition, and other weapons remains one of the most enticing and murkiest parts of global trade, and most difficult, and morally-challenging, to evaluate as an opportunity-- and begs calls for more transparency.

The data is especially opaque in China, which has pledged to boost its military might as it increases its economic influence around the world. Although data indicates that the country exported only $95.9 million worth of weapons during the first nine months of 2017, SIPRI and other research groups estimate that the real total is much higher, especially when including shipments to Africa.
