His problem is obviously with both US politics and US culture, in fact he hates america so much that he does not want to live here and does not want his children to live here either in the long term. Since he brings up his wish for his kids to experience america, form an identical opinion to his (interseting "progressive" parenting style isnt it) and then leave we must assume he is looking in the long term - unless he means they form such an opinion from between ages 2-9 we must assume that he is thinking beyond the Bush presidency as well, meaning his kids come to the USA as older teens and make their own decision with some life experience. This means his real problem is with America and not just Bush policies since they can be gone as soon as next year if he looses or ion five years at the latest - eitherway his oldestt will only be 9 years old then anyway.
So yes his problem is with America in general and not just with Bush - that much is clear
Then i just find it funny that since he hates America so much with such passion as to leave it and insist his kids hate it too that he still finds it morally OK to earn his living in the USA. Its like some refugee from the nazis, you lefties will love the comparsion no?, still making his living in Germany as a rich entertainer while publicly criticizing the culture and govt.
If he was a true disssident why not swear to not make US moves with US studios? Why contribute to millions in corporate tax revenues to the evil US government by making such spectacularly succesful and entertaing films as Pirates Of Carribean?
The guy is full of **** and a hypocrite...
