You cannot fight a WOT but then leave the borders open and allow millions of Muslim immigrants to come here. That is completely suicidal.
Ron Paul is one of the few candidates who support REAL border security and reform of existing immigration laws. No, not the "pathway to citizenship" crap, not the "guest-worker" BS, he wants the borders MILITARIZED.
All of our troops should be out of the Middle East by 2010, IMO. We should kill as many terrorists as possible and then tell Iraq and Afghanistan they need to crap or get off the pot, and tell the region that if we're ever attacked again or even think about it, they'll be a smoking pile of rubble. We need to stop sticking our noses into this stupid region that's been at war since biblical times.
