SDI: Strategic Defense Initiative

SDI (Strategic Defense Initiative) is a very controversial and difficult subject to discuss. Especially since everyone, including myself, likes to believe that the Soviet Union is truly changing. However, the changes are taking place slowly, and there is still a lack of trust on both sides. Too many people still remember the cold war. So there is, unfortunately, still tension between the US and the USSR.
At first, a computer controlled defense system that would provide an impenetrable shield against nuclear missiles seemed like wonderful idea, an idea that could actually make nuclear weapons obsolete. However, when people began to think about the technology that "Star Wars" would require, many became skeptical. Scientists, programmers, and engineers began to figure out what would be necessary for such a system, and soon came to the conclusion that we don't yet have the technology necessary to make SDI one hundred percent effective. Obviously, a defense against nuclear missiles is worthless unless it is completely effective, because if only one missile were to get through, there could be millions of people killed.
To move your cross hair, use the CURSOR keys. Pressing the SHIFT key and one of these keys simultaneously will make the cross hair move in larger increments. You use this feature to zip from one side of the screen to the other. (If you have one of those new keyboards with the new cursor keys, don't use the NEW cursor keys, since they won't work with the shift key. Use the old cursor keys, the ones on the number pad) On all IBM/compatibles, if you have NUM-LOCK turned on, the function of the shift key will be REVERSED.
To destroy a missile, move your cross hair to the front of the missile's trail. When you have it lined up, press the "Z" KEY (think "Zap") to fire your satellite's laser.
The easiest way to position your hands is to place your left index finger on the "Z" KEY (for firing) and your left middle or ring finger (depending on the keyboard you have) on the left SHIFT key. Use your right hand to press the CURSOR keys.
