Russian strategy seems to center on maintaining Putin's popularity at home; building a strong military capacity in special forces, nuclear weapons, and advanced submarines; pressuring nearby nations to join various defense and customs pacts dominated by Russia; and pushing back on the U.S. wherever convenient.

If we discover through a thorough and unbiased investigation that Russia has indeed attacked our electoral process directly with the intent to influencing the process, our response needs to be robust, rapid, and proportional. This will shape our relationship with Russia profoundly.
