The new law of immigration in Arizona was discontinued by federal judge (Susan Bolton), however , she thinks that will affect the relationship between The US and other countries. There are many people refuse this law, there refusing was appeared when they got together in Washington, DC and other cities to say no for it. Additionally, there are some governors with this new law and others against.
Questions:
1- Why does this law appear now?
2- Why does Arizona state just decide this law?

I think the USA is a strong country, that strength came from the difference, so it should be like this style.
