Wars of aggression, like Hitler's wars in Europe and against the Soviet Union, and Putin's war against Ukraine, are also crimes under international law. At this moment, we are facing the possibility that Russians committed genocidal crimes in their offensive against Kyiv. It is sad to say that this kind of discovery is not unusual in the history of warfare.
In some sense, this war is a wake-up call for Europe. What are the most important lessons to be learnt for the future of Europe in terms of strategic autonomy?
The lessons for Europe are legion. The first and most important is that Europe needed and needs a unified security policy towards Russia and its revanchist aims. As mentioned above, unified and full-fledged support of NATO, including meeting budgetary commitments, is absolutely necessary for Europe to be able to influence Russian policies and actions. Good will and trade will not suffice. It is not enough to rely on Article 5 of the NATO Treaty to ensure that Europe will be ready in the case of Russian aggression. Active steps towards reinforcing front-line countries, such as have been taken in the past month, will need to continue into the indefinite future. European countries need to do better at developing, building, and delivering new weapons systems to their NATO partners.
Once again, relying on the Americans is not enough. Europe needs to adopt a serious security posture of its own.
In this connection, the European Defense Union also requires funding and serious recruitment and training. There will be times when NATO might not be the right instrument for guaranteeing European security. That is when the European Defense Union can step in. Certainly, another important lesson is the need to reduce European dependence on Russian oil and gas. Policymakers and outside observers have been saying this for decades. In dealing with sanctions against Russia, I would agree that every country, including those in Central Europe, need to think about their own interests and should not be bullied into joining sanctions that they deem injurious to their own people. Still, it would be a good thing for Europeans to show solidarity about the sanctions regime, as best they can. While there are other specifics that could be mentioned, one general proposition should be observed.
Europeans need to disprove the adage that “Americans come from Mars and Europeans from Venus,” in short that Americans fight wars and Europeans are pacifists.
The traumas of the Second World War are a powerful reminder of the horror of war. But the way to prevent war are strong defenses, a readiness to confront aggression, and a willingness to sacrifice a measure of economic well-being for the peace of the continent.
