This is a multi-faceted problem set, so let me just take on a very narrow, focused view.
The COVID-19 pandemic has affected everyone equally and certainly has affected potential adversaries. In this great power competition setting that we're in, it's certainly affected countries that may have northern or Arctic ambitions as well. We saw no degradation in our ability to project our forces. What you would anticipate happening in the Arctic, with our great Canadian Rangers and with the deployments of navel assets in activities such as Operation Nanook, has continued with no degradation.
