I am not so sure that nobody cared about politics in the USA. I think that most of the world has regarded the US as the place to emulate. Zionists went to the USA in part because they had not done very well in Europe and in part because the US wanted control in the middle east. Also because there are quite a few Christians in the US who think that once the Israelis go back to their "promised land" the Apocalypse/Armageddon will happen and they will "rise naked to the right hand side of God".
