Greater economic development and democratic consolidation are key to stability.

Intro: The world is, and always has been, a dangerous place. We should not hide from those dangers

The British Defence Secretary, Sir Michael Fallon, recently spoke candidly about the condition of Afghanistan and the possible continuing consequences for Britain. Sir Michael deserves credit for raising the issue so openly. The country remains a base for international terrorists who mean us harm, he said. He also suggested that the ‘collapse’ of the fragile state could send millions of young Afghan men west in a new phase of European migration that would inevitably affect the UK.

Such a premonition paints a grim picture, but all the more so because it comes more than 15 years after British troops were sent to Helmand Province in Afghanistan following the 9/11 attacks of 2001 on the US.

The military mission, at first, was to render ineffective an international terrorist group that meant us harm; yet, today, al-Qaeda under various Arabic guises and splinter groups remain operably active. Later, the British mission shifted to one of nation-building and the reinforcement of Afghanistan’s fragile and desperate government. It was done so to avoid precisely the sort of collapse that Sir Michael now refers too.

To some, the lack of significant progress in Afghanistan will be proof that Western military interventions in poor and unstable countries are doomed to fail. Iraq, and more recently Libya, the nexus of why Europe is facing unmitigated levels of migration, might equally be cited as additional evidence for that case. What is clear is that all three interventions have been flawed, suffering from a lack of political leadership and, in some cases, extremely poor military planning.

To those who believe Britain has no inalienable right to remake the world, Theresa May’s professed scepticism about wars of liberal intervention will be a welcome shift in approach when it comes to foreign policy. Yet, healthy doubt about military adventurism does not necessarily mean a British retreat from the world.

The defence secretary’s words and rhetoric are a stark reminder, whether we like it or not, that the consequences of previous Western interventions continue to this day.

They must be dealt with, not ignored. We should indeed go on working to support a democratic government in Afghanistan, including the aiding of its security forces if needed.

In Iraq, where government forces are pushing back Islamic militants in Mosul, has shown that with continued Western backing, local military units can take responsibility for securing their country.

Britain’s role in Afghanistan must continue, and may have to expand by putting boots back on the ground there. If that means spending more on defence, for the security and stability of the West, so be it. The world is, and always has been, a dangerous place. We should not hide from those dangers.
