From the arms industry's point of view, what should have happened then was that western states would have spent plenty of money replacing the expensive missiles and guided bombs they used, while a pro-western Libya established after Gaddafi had been lynched would have wanted to build a modern air force, army and navy, buying lots of weapons from those friendly western states that had helped terminate the previous regime.
A lucrative desert war
The first part worked fine but the second didn't. Libya descended into disarray - but even that disaster was not all bad news for the arms trade. One of the grim results of the 2011 war was that arms cascaded out of Libya across the Sahara and Sahel, greatly boosting the numerous Islamist paramilitary movements across the region. To counter this, thousands of western troops are now deployed across the region, air and drone strikes are commonplace, millions of dollars' worth of precision-guided munitions are being used and vast amounts of equipment are being provided to many governments.
It is a hidden war that is very good indeed for business and is now being enhanced by a sudden escalation of the burgeoning civil war to the north in Libya itself. There, the UN-backed Government of National Accord in Tripoli is facing the forces of the self-styled Libyan National Army from the east of the country, headed by Haftar, a former Gaddafi military leader. In the past few days Haftar's army has moved closer to Tripoli itself as it tries to take over the whole of the country, even as UN personnel seek vainly to arrange a ceasefire.
The government has recently been equipped by western states. In one episode over the weekend government forces shot down a Libyan National Army aircraft. Since then, the LNA has moved close enough to Tripoli to fire artillery that has killed at least four people and wounded twenty in the southern district of Abu Salim. Thousands of people have been displaced from their homes with at least 150 killed in this most recent bout of the war.
Wealthy supporters
One aspect of the war is particularly good news for the arms industry. While the conflict is between the government and the LNA, above them are outside actors. Much of the weaponry of the UN-backed government comes from western states, with Italy being the most prominent. That is one of the reasons why the government is proving more resilient than some had expected, although there are also regional supporters involved, including Qatar.
On the other side, the insurgent LNA is strongly backed by Egypt and the United Arab Emirates. They both want a united Libya under Haftar or another strong leader who will suppress dissent and be especially hard on Islamist paramilitaries. This backing extends to their direct military involvement, with UAE air force strike aircraft aiding the rebels as they move towards the capital.
This is where history repeats itself: the UAE is one of the heaviest buyers of western aircraft and munitions in recent years, second only to Saudi Arabia among the Arab states across the Middle East. In short, the western-backed government is fighting the western-equipped LNA. However it ends, and however many people are killed, injured or displaced, the arms companies and their shareholders will come out of it well.
