Ron Paul is indeed, along with Pat Buchanan, completely blind to real threats on the international stage. Even Ron’s hero, Thomas Jefferson, took the US to war within weeks of his election to President, but Ron can’t seem to discern the need for aggression at certain times, from his ideological bent against all forms of war making.
His son’s problem is that Rand has the same ideological addiction to “let’s swing open the doors” view of immigration. Rand believes, as Libertarians do, that we should not have borders at all.
Au contraire Pat and Paul are among the few not duped by the war mongers who want to drive the USA into existential wars in the middle east and Russia. The threat to the USA is China not elsewhere.
