The USA is not seriously threatened. The Republican party just wants people to be afraid... That's how they get votes.
The USA is always threatened since we are a major power. Also thats what people were saying BEFORE 9/11 happened (cept for the republican part.) My point is that if you aren't in these terrorist groups than how do you know what they are thinking. Yes, we should feel threatened and take everything serious, but we should not panic.
