On this day in 1949, 12 European and North American ministers gathered in Washington, D.C., to commit their nations to one another’s defense. With the scars of the Second World War still raw and new threats looming, they pledged to safeguard the freedom of their peoples.
As the North Atlantic Treaty Organization turns 75, and as the foreign ministers of a founding nation and the newest member, we believe that NATO is as relevant to North Americans and Europeans as it was in 1949—and that it is stronger than ever.
This year, two-thirds of NATO allies are expected to spend at least 2 percent of their GDPs on defense. Our unity in backing Ukraine has surprised Russian President Vladimir Putin—and sent a clear message about our determination to stand up for our values to those watching elsewhere.
This week, NATO holds its first ministerial meeting since Sweden became the alliance’s 32nd member. The expansion is good news for the whole alliance. Sweden is a highly capable ally, with defense spending surpassing 2 percent of its GDP. It has years of experience of training and operating with NATO allies.
We should not underestimate how significant a decision this was for Sweden. For two centuries, Sweden opted for military nonalignment. Fundamentally, there were two reasons behind Sweden’s decision to join NATO now.
First, because the world has changed. Putin’s demands for a sphere of interest and his illegal invasion of Ukraine challenged the whole Euro-Atlantic’s security. The world has become more dangerous, with consequences for us all.
Second, because of how effective NATO has proved. It is the world’s most successful alliance, deterring the threat from the Soviet Union during the Cold War and remaining united during the decades that followed. NATO protects its citizens from Seattle to Stockholm, guaranteeing our collective security and thereby enabling our collective prosperity.
For 75 years, this strength and unity has deterred any state from risking the alliance’s collective might in war. When al Qaeda terrorists launched the horrific attacks of 9/11, NATO members immediately stood in solidarity with our U.S. allies. Our efforts against terrorism must continue.
As the world changed, it made sense for Sweden to turn to the alliance. Sweden will be safer in NATO, and NATO will be stronger with Sweden.
Still, the threat from Putin is not going away. We have to equip NATO for a long-term confrontation with Russia. We must make Sweden’s accession, hot on the heels of Finland’s, a spur for further action in order to remain strong and unified.
With this in mind, we see five pressing issues for NATO leaders ahead of the alliance’s summit of heads of state and government, which will be held in Washington in July.
First, all allies must invest more.
Britain hosted the 2014 summit where all allies committed to 2 percent defense spending. (Only three allies met the 2 percent figure that year before the commitment.) Both Britain and Sweden are proud to fulfill it. It is vital that the whole alliance plays its part in ensuring our collective security—we have to be able to deter and defend against aggression.
We should also recognize the transformational potential of such investment: pounds, krona, euros, and dollars spent on producing equipment and munitions in industrial heartlands across NATO nations. Over the past two years, for instance, allies have bought $120 billion worth of weapons from U.S. defense companies.
Second, all allies must adapt more.
The world is changing, and so is conflict. We can see this on the battlefield in Ukraine: Twenty-first century technology is vital to Ukraine resisting Putin’s nineteenth-century imperial ambitions. We must invest in cyber and artificial intelligence.
Third, we need to assist Ukraine.
Ukrainians are fighting not only for their own freedom and democracy, but also for the security of all countries in NATO. While NATO will not be drawn into a conflict with Russia, it is crucial to provide Ukrainians with the strong and predictable support that they need to win the war.
Fourth, NATO must engage more with the world.
We need to sustain our focus on our partnerships with the most vulnerable partners—notably Ukraine, but also Bosnia and Herzegovina, Moldova, and Georgia. But while NATO is geographically bound in the Euro-Atlantic, the threats that it faces are not. We must respond to threats, wherever they come from in the world.
That means being active in both the High North and the Mediterranean, as well as the Baltic and Black Seas. We also need to engage more with partners in the Indo-Pacific.
Finally, all allies must commit. Commit to making these changes for our collective benefit. While we pay tribute to U.S. leadership of the NATO alliance over the past 75 years, it is the combination of North American and European strength that has proved to be the force multiplier. There must be a stronger Europe within NATO.
With Sweden joining the alliance, that force-multiplier effect has grown even further. By staying strong and united, NATO can grow further still.
