- It may eventually protect us one day from a nuclear attack by a rogue or terrorist nation such as

the technology improvements.
- It can defend us against missile delivery of chemical or biological weapons.
- The psychological impact on enemies is more powerful than the defense system itself.
- Military and scientific jobs are created from the project.
- Funds spent on the project are pumped into the economy.
- Military technological advances and research often lead to valuable civilian advances (e.g. the Internet).
- The missile defense system may discourage terrorist nations from even trying to develop nuclear weapons.
- The system has little chance of success against a massive scale attack or against a terrorist strike.
- The towering costs for a system that may never be used would be better spent
on fighting poverty, improving
- Spending large amounts of money on these types of projects leads to unwinnable, useless arms races.
