The scariest thing is that the Americans seem to be completely in love with Palin precisely because she is 'normal'. "She's one of us" they say, She's not elitist, we like her 'down to earth' values. But in what other profession would you ever give someone huge responsibility because they are 'like you', rather than having the necessary skills? Would you want a pilot who is a 'good guy', or an excellent pilot? Would you want a brain surgeon who plays ball on Sundays, or who has trained for more years than anyone else?
Another concerning thing is Palin's confidence - she seems to have no sense of her own limitations. She's up for anything. Everything is an immediate "YES". No financial experience? "no worries - i'll guide the country through this difficult period". No international political experience, and I only just got a passport in the last few months? "I'll handle the crisis in Iraq and Iran". No medical training? "I'll operate on this wounded soldier right now!".
To be honest I would be a lot more comfortable if she had some idea of her own inexperience. But her enthusiasm combined with her extremely right-wing values such as "No abortions - even if the mother is under-age and has been raped", and her belief that everything happens due to the will of god, and not because of complex political interactions, make her a ticking time bomb in international relations. If she ever controls the world's most powerful army and largest Nuclear weapons arsenal, then I think we all need to be very, very afraid... (watch this video to laugh and shudder)
