Is the US going to stop messing around in other countries with their military, the NSA spying and CIA ? That actually sounds very tempting. Maybe we will pay for a wall, maybe even a dome.
After we take all the resources and the money from the US that you still own all the other countries in the world, their should be more than enough money to build that dome.
Here is a question: as many know, the US makes a mess of the middle east with their military forces because of natural resources. Why would they need to do that if there are enough natural resources in the US ? Have you ever thought about that ?
