Back in the 40's civilization's very existence was threatened by Naziism.
That was quickly followed by Communism.
Now it seems we are threatened by radical Islam.
After that, we are scheduled to be annihilated by a rising China.
If your only concern is the defense of this country, then you will have plenty to worry about from now until the end of time.
Meanwhile, we do seem to have enough time and space to deal with the myriad other concerns that distinguish the USA from the rest of the world, and make the USA worth defending.
On almost all of those issues Ron Paul is solidly in favor of what the vast majority of Freepers support.
I am not planning on voting for him, but he is not a complete lunatic, he is not a democrat, and he is far better than all of the democrat candidates and many of the republican ones.
You might want to read, or reread, Orwell's "1984" if you want to see the sort of world that your blindered view leads too.
Of course there are other issues but RP is not willing to defend the USA so the other issues will be moot.
