Abandon your allies, and you will find yourselves alone. Abandon mutual defence treaties and find yourselves at the mercies of your enemies.We should be the friend of liberty everywhere, but the guarantor and provisioner of ours alone
Pretend the rest of the world does not exist, and that your defence and welfare comes with the cooperation of other nations, and you will be deaf, dumb and blind.
Right now your satellites can relay information to you 24/7 because of relay stations.Those stations are on foreign soil as a result of defence treaties.
Remove those stations and the moment they cross the plane of the ecliptic, you are an open, tempting target.
No DEW line.
No foreign intel.
No cooperation between your NSA / CIA/ DIA/ DEA and foreign governments.
See that line called the Equator? You have enemies beyond that line.
Who do you think it is that watches your back whilst you sleep?
