The cold war is over. Just what is this threat by Russia? Are they going to invade us? Are they going to start some other major war? No, they cannot. They do not have the infrastructure, the wealth or the population to undertake such actions. Russia is not a threat to us, and we need to recognize it, and move to a better relationship.
Now China and the Middle East - those are potential threats and what we need to prepare for and be wary of.
