Discussing the recent wave of hybrid attacks against Europe, Sijbren de Jong told La Voz de Galicia that although Europe is not officially at war, it is a fine line. "You can launch low-intensity threats against your adversary, preparing the ground with small actions that aren't attacks to wear them down. I think we are in that phase," he said.

According to Sijbren, it is important to understand that one reason certain actors carry out hybrid attacks is to learn how we respond, how long it takes us, what we prioritise, where our resources go, which actors and agencies are working to resolve the situation, and how much time, assets, personnel and money the response consumes.
