Begin to look into a space based ballistic missile defense system to protect the US from foreign threats.

The world is a troubling place. But a space based BMD is the answer, not only does it deter other countries from attacking, but it also defends if needed. We have the technology to do it already. It might need to take the form of a lazer. it travels at the speed of light, isnt affected by gravity, can protect against collateral damage, and is very cost efficient compered to the current method. Another use is also to clear space debris and protect our satellites. There are plenty more reasons why, do some research!
