States will base decision on whether or not to deploy space weapons on their own rational calculus
To argue that states must follow Washington and deploy space weapons out of self-interest is to ignore the fact that self-interest has many faces. In the end, foreign officials must weigh personal, national, and party priorities and strategic requirements, understand political tradeoffs, and assess whether the national treasury and domestic resources could support plans to "match" U.S. weapons.
Haiti's security needs will not match those of Serbia, Iran's will not match Canada's, and India's will not match those of the United States. Space control weapons, one must conclude, would not fit very well in the defense strategies of many nations. Foreign leaders, in other words, are not automatons. Between action and reaction always lies choice.
