I want to add a point. The cyber-aggression that Russia uses in Ukraine, they will perfect and use against us. They already have.
If I can make a provocative historical analogy, the Spanish Civil War was the testing ground for new methods of aggressions to be used first in Spain and then elsewhere by aggressive powers.
Many people in the west, including in the United States, believe that Russian aggression against Ukraine had nothing to do with them. They have now discovered their error.
We have all seen Russian cyber-attacks against the United States, against west Europeans, as well as against the Baltics, the Estonians, the Ukrainians and the Poles. We need to study what the Russians are doing and prepare both defensive measures and potential sanctions steps, acting as a community of the western democracies, and explore other steps to prevent the Russians from operating with impunity.
