We've seen what the reaction of resets by previous U.S. presidents has brought, and it hasn't brought a more co-operative Russia. Unfortunately, we've seen through the past that Russia only understands when there is equal strength on the other side and not necessarily this strategy of trying to engage. Unfortunately an engagement strategy without deterrents is ineffectual. Unless there are costs for a certain activity, essentially that is the strategy that needs to be implemented—a strong deterrence strategy with Russia.
