Russian military aircraft once again violated NATO airspace—this time over Estonia. Outrageous. Russia’s destabilizing activity is expanding into new countries and directions. They use every tool: from interference in political processes, as in Romania and Moldova, to violations of airspace, as in Poland, Romania, and now Estonia.

These are not accidents. This is a systematic Russian campaign directed against Europe, against NATO, against the West. And it requires a systemic response. Strong action must be taken—both collectively and individually by each nation.

Russia must feel increasing pain from the world’s pressure, first and foremost through its economy, and that is best ensured by sanctions. At the same time, Russia’s war losses must continue to rise, which is best achieved by a strong Ukrainian army.

I thank everyone who helps. Europe, the United States, the Group of Seven—strong action is required from all.
