I think the fear many Americans have is with merit. Obama wants to turn this country into another Europe. Socialist, cowardly, unwilling to engage in any prolonged conflict with anyone and would rather be liked by the enemy instead of confronting the enemy. I'm not sure that we get nuked when he takes over. But I will tell you one thing, we will 100% be attacked again on our shores. Put it in the bank.
PS- Oz, saying 911 took place when Bush was in office is very misleading. He had barely hung up his coat in the oval office when we got hit. Most of FBI, NSA, CIA etc. was exactly in tact from the Clinton administration & the scum who attacked the WTC in 1993 began planning for the 2001 attack almost immediately after their first attack was unsucessful. The Clinton administrations idiotic decision to try those responsible for the 1993 attack in a regular civilian court was as much to blame for the 2001 attack as anything else ( Beyond Clinton not taking Bin Laden as a threat seriously, cutting military funding, etc. etc. etc. I could go on forever).
Little known fact: One of the perpatrators of the 1993 attack was caught after going back to the rental car place where he rented the van he used to move the explosives to get back his $50 deposit.
