4321go... I am not sure America has any "nationalist threat" at home. We have the Republicans who are in power, and they criticize the Democrats, and spread false rumors, and I guess the same is true of the Democrats towards the Republicans, but this is normal.

The American government's focus is almost entirely on external Islamic fundamentalists who are planning attacks around the world, including attacks inside the United States. In doing this, though, I have to say that the American government has curtailed our basic freedoms and rights and liberties, slightly... but noticeably. For example, the government can now enter anyone's house and take anything or search anything without letting the owner know. This behaviour is entirely new for Americans.

There are many other signs that America is changing in this "restrictive" direction, so I find it humorous when American government officials go to China and demand that the Chinese give more freedom to their citizens!!!
