NATO ALLIANCE

Intro: If Trump follows through on his threat to pull out of the alliance, the West will face its most profound crisis in 80 years

For eight decades, NATO has weathered internal disputes, enemy plots, and shooting wars in Bosnia, Kosovo and Afghanistan. America’s departure of this historic alliance would be the biggest divorce in history.

If Donald Trump acts on his threat to finally pull the US out of NATO – having said publicly that he is “strongly considering pulling out” after allies failed to join his war on Iran – the transatlantic family will be torn asunder.

At which point, the club that calls itself the most successful alliance in history may as well close its doors.

And the pain could match that of the most acrimonious of break-ups.

The numbers are stark enough: the United States alone accounts for more than 60 per cent of NATO’s total defence spending and provides the bulk of the alliance’s firepower, particularly at sea, in the air, and in nuclear deterrence.

The US has 1.3 million active military personnel – a full million more than Turkey, the next largest NATO force.

The United States is, however, not simply the largest and richest member of the club. It is the linchpin, the tent pole around which the entire edifice has been constructed.

It has logistical capacities in airlift and shipping, as well as satellite and signals intelligence, that other NATO allies rely on to get them into battle and help them fight. And it has always provided the leadership that has kept the alliance together.

Europe

The most profound threat would be for European members, the primary beneficiaries of the Article 5 promise that “an armed attack against one or more of them in Europe or North America shall be considered an attack against them all”.

For the first time in 80 years, they would have to face Russia shorn of that basic security guarantee, even as war rages on the continent.

Trump allows other NATO countries to requisition US kit for Ukraine via a programme called The Prioritised Ukraine Requirements List, but has curtailed direct US military aid to Kyiv.

Nonetheless, Moscow has not doubted the seriousness of the NATO alliance. For four years, it has avoided risking a direct confrontation with NATO powers, to the point of refusing (for the most part) to bomb the airbases and railway depots in Poland that supply Ukraine.

But remove American conventional and nuclear power from the equation, and the risks of doing so suddenly look much more palatable. Vladimir Putin has long made the destruction of NATO and creation what he calls a “new European security architecture” one of his dearest and cherished ambitions.  

That does not make a direct Russian attack on Europe inevitable, should the US abandon the alliance. But the chances of Putin taking a gamble would increase substantially.

Greenland and Canada

Quitting the alliance would not only absolve Trump of the obligation to come to allies’ defence. It also opens the way – at least in theory – to one would-be former ally attacking another, a scenario NATO itself would never have been able to survive.

Canada, in particular, would face difficult new realities. Trump, who has ordered attacks across 13 countries since he returned to the White House, has coveted their country (a NATO founding member) as a future “51st state”. Suddenly uncoupled from its enormous neighbour and security partner, Ottawa would no longer live with the certainty that North America is a safe and secure home.

War is perhaps most likely in Greenland. In recent weeks, it emerged that the Danish military had secretly prepared to repel a possible American assault on the island amid repeated threats from Trump to annex it.

Troops were equipped and ordered to blow up key runways and even flew in blood bags to simulate treating the wounded from the anticipated battle.

These nightmarish prospects present serious dilemmas for Canada and Denmark’s remaining allies.

Would Britain, France, and Germany send troops and ships to fight off an American invasion? Or out of dependence on and fear of American might, would they turn their backs? Leaders in Britain will be praying that they never have to make such a choice.

Everything from Britain’s nuclear missiles, which must be serviced at American facilities, to GCHQ’s signals intelligence network, which overlaps with the US National Security Agency, is enmeshed in the apparatus of the US security system.

America

Like any major break up, the pain would not be one way. America, too, would suffer.

Since its founding, NATO has allowed the US to project power globally. US airbases in Britian and Germany, for example, are currently being used for American operations against Iran.

NATO states also house and accommodate American early warning systems. It is the UK and Norway, for example, whom the United States relies on to keep an eye on Russia’s nuclear missile submarines operating out of Kola Peninsula and the Barents Sea. And while some NATO members – France, Spain, and Italy – may have baulked at the war with Iran, the alliance has proved vital in other US-led engagements.

Its member states joined the Americans in ending the Serbian genocide in Kosovo in 1999, for example, and in the 20-year campaign in Afghanistan. Many also showed up for both the first and second Gulf Wars.

If the United States does find itself embroiled in the much feared and potentially epochal war with China in the Pacific, such former allies will be missed.

The consequences

For these reasons, and the fact that Trump cannot withdraw from NATO without approval of a two-thirds Senate majority or an act of Congress, it is possible the worst fears about transatlantic relations may not come to pass. Indeed, even in a future without the formal North Atlantic alliance, American will need allies and to maintain bilateral ties.

And since Trump’s public doubts about NATO and his threats against Greenland have already undermined the deterrent power of Article 5, perhaps losing it altogether would not do much more damage.

Conventional defence spending in Europe is already rapidly increasing, especially in the east and north of the continent. No sensible Russian general is likely to believe a fight with Poland would be a walk in the park.

Although small compared with America’s, Britain’s nuclear arsenal, which, unlike the French one, is committed to the defence of NATO, is potent enough to act as a serious deterrent. The UK would, however, have to develop a domestic delivery system if it is to eventually wean itself off dependence on US Trident missiles.

There is also the suggestion that the alliance could continue in some form, even shorn of the US. Trump’s repeated attacks on the alliance have already prompted some British and European strategists to think about how to preserve it without America.

The remaining allies could, for example, retain the North Atlantic Council, NATO’s main decision-making body, and the mutual defence clause.

Perhaps, then, there is a very narrow but plausible path to enduring a divorce and not suffering too greatly.

But should Trump or another incumbent president come to see Canada and Europe as enemies, the world will change profoundly.
