NATO, despite its changes over the decades, has always had the primary purpose of deterring any military attack from Russia/the Soviet Union. It was also a power magnifier for the United States, a fact which Trump and his unilateralist supporters don’t seem to understand or care about.
Europe’s current drastic readjustment
In the often-grim game of great-power politics, countries engage in an ever-evolving process of calibrating and recalibrating threats and potential threats. They also have to engage in an elaborate process of signaling and reading signals that countries send to each other, not least in their military capacities and priorities. Russia currently is engaged in a big war of aggression against Ukraine and has been since 2022, with a prelude in the illegal seizure and annexation of Crimea in 2014. Russia also sees its international interests as involving what it calls its “near abroad."
The NATO countries of Estonia, Latvia, and Lithuania were once part of the Soviet Union proper, as were Ukraine, Georgia, Moldova and others. NATO allies Poland and Hungary were part of the Warsaw Pact and therefore of the USSR’s European field of influence. The USSR used military force against both to boost Communist control in those nations and reinforce Soviet dominance in foreign policy.
None of this means that Russia has any immediate goal or intention of taking over or attacking any of those countries. But all countries have to evaluate both the intentions of international adversaries and their capabilities. The former is broadly considered the concern of foreign policy officials and analysts, the latter primarily a concern for the military. There was a huge chance in 1989 and immediately following years to dramatically limit and reduce military capabilities and to pursue various arrangements to improve political relations on both sides of the former Cold War. They were only partially fulfilled and inadequately pursued. But that’s a much longer story.
Joe Cirincione wrote on February 4 about a sad milestone that is now already past:
[T]his week, the New START treaty will expire. It is the last nuclear reduction pact remaining. For the first time since 1972, when Richard Nixon negotiated the first treaty limiting US and Soviet nuclear weapons, there will be no limits and no inspections on the two nations that possess over 90 percent of the world’s nuclear arms.And the current war against Iran along with Russia’s war against Ukraine provide a strong incentive for more countries to acquire nuclear weapons to deter attacks from rogue nuclear imperial powers.
As a result of multiple accords, negotiated and supported by Republicans and Democrats for 54 years, the nuclear arms race was restrained and then (with Ronald Reagan’s Intermediate Nuclear Forces Treaty (INF) of 1988 and George H.W. Bush’s Strategic Arms Reduction Treaty of 1991) reversed. We went from almost 70,000 nuclear weapons at the height the Cold War in the mid-1980’s to about 12,000 today.
That era is over.
There have not been any further treaties negotiated since Barack Obama’s modest New Start treaty in 2010. Neither Trump nor Putin appear interested in nuclear restraint. Under Joe Biden and Donald Trump, the United States is now committed to spending $2 Trillion on new nuclear bombers, missiles, submarines and warheads. A likely result of the end of New Start is that “Trump will sign off on more money for new nuclear arms,” writes Tom Nichols in The Atlantic. [my emphasis] (1)
It’s also a huge new security issue for Europe because a key part of the West’s nuclear deterrence strategy against Russia has been the MAD (Mutually Assured Destruction) assumption that if either Russia or the US initiated a nuclear war against the other they would know that the other side would retaliate with a comparable nuclear strike. That assumption extended to all of NATO with the US providing the most important part of the “nuclear umbrella” for all of NATO. European NATO members can no longer count on the US maintaining that guarantee for Europe.
That means that western Europe’s two nuclear powers, France and non-EU member Britain, will need to compensate for that long-term loss of confidence in the US position. It also means Europe is having to increase its conventional military forces, which it is now doing. That is a grim matter and makes public scrutiny and criticism of military programs more important than ever. If the post-1989 European situation had gone a different way, things could have been very different.
In this current, rapidly-evolving security environment in Europe, European leaders are in a complicated balancing act. Developing a more robust defense structure as a deterrent against current or future malign Russian intentions means that they have to set up a real alternative to current NATO structures, which have been built around American command structure, weapons (2), and intelligence capabilities. And that can’t be done overnight. At the same time, they have to been concerned with explicit US military threats against European powers, likely the recent threats of war against Denmark.
The Iran War and the European strategic pivot
Which means that they have a strong incentive to not only downplay diplomatic disagreements among themselves, but also to avoid alienating the US, at least as far as that is possible given the current extremely erratic and reckless President.
EU Commissioner for Foreign Affairs Kaja Kallas has been striking a cautious tone as in this Bluesky thread:
It would be welcome to see the Europeans collectively through the EU or some substantial portion of it to condemn the illegal war of aggression launch by the US and Israel against Iran. You know, values-based-world-order and all that. It’s also worth saying that the Nuremberg Trials established the concept of “aggressive war,” i.e., unprovoked attacks on other sovereign nations, as a war crime. Stephen Ratner wrote in 2007:
Aggression in international law is defined as the use of force by one State against another, not justified by self-defense or other legally recognized exceptions. The illegality of aggression is perhaps the most fundamental norm of modern international law and its prevention the chief purpose of the United Nations. Even before the UN, the League of Nations made the prevention of aggression a core aim; and the post-World War II Allied tribunals regarded aggression as a crime under the rubric crimes against peace. [my emphasis in italics] (3)The world – including the United States – does need a stable set of international laws and standards. So does everyone else.
Beth Griech-Polelle writes:
International law is still limited by international politics, and we must not pretend that either can live and grow without the other. But in the judgment of Nuremberg there is affirmed the central principle of peace that the man who makes or plans to make aggressive war is a criminal. (4)After their responses to the Gaza genocide, it’s a safe bet that Europe will not be collectively demanding war crimes trial against US officials on charges of planning and waging a war of aggression against Iraq. Although they certainly should!
Still, as this report from Scott Lucas from the Polish news channel TVP World notes (5), the British government has raised international-law concerns over the US-Israeli attack on Iran. Albeit in about the most delicate sense of saying it was up to the US to lay out the legal justification for the war. (At least it’s not like Tony Blair shamelessly assisting the US attack on Iraq in 2003.)
In general, the Europeans are showing various degrees of public restraint in their public statements on the issue. Europe does have things like this to worry about: “Russia Attacks a NATO Country in a War Game. It Doesn’t End Well.” (6)
And not so very long ago western Europe’s two nuclear powers (Britain and France) together with Germany, France, Poland, Spain, and Italy issued a public statement on X/Twitter warning the US that they were ready to stand by their mutual defense commitments to Denmark if it was attacked by the US. That list includes western Europe’s two nuclear powers (Britain and France) and the countries with its six biggest conventional armies: Britain, France, Germany, Spain, Poland and Italy. That deterred an American attack, at least for the moment. But they are also playing a delicate diplomatic game. At least the Europeans, unlike Trump, are very capable of doing actual diplomacy. NATO member Türkiye has also had friendly relations with Iran.
This short Reuters article reports on the British Prime Minister providing reassurance to the government of Cyprus:
[British Defence Secretary John Healey] cited two missiles fired in the direction of Cyprus, although he added: "We don't believe they were targeted at Cyprus."Notes:
Cyprus President Nikos Christodoulides said British Prime Minister Keir Starmer had called him to discuss regional developments.
"(Starmer) confirmed clearly and unequivocally that Cyprus was not a target," Christodoulides said on X.
"We are maintaining direct communication. All relevant authorities are fully engaged and monitoring developments closely." (7)
