First of all, the warmongering is affecting us all. My country, Holland, joined the war in Iraq which really bothered me.
Second, the weakening of the US Dollar and American economy affects the world economy. Dr. Paul's ideas have taught me a lot of how monetary economy works (as did Lew Rockwell's writings).
And last but not least, I have discovered Ron Paul as an example to all politicians, I have never seen a politician with so much integrity. I'm even thinking about translating his ideas to some political movement here in Europe. Before Ron Paul, I never realised what your Constitution really means, and what a great set of principles it is to any society aspiring to be free.
