America is the only developed nation that has a 2,000-mile border with a developing nation, and the government's refusal to control that border is why there are an estimated 460,000 illegal immigrants in Arizona.
If the United States federal government would enforce its own laws against being in the country illegally, then Arizona wouldn't have bothered to pass this controversial law. If you would look for someone to blame for the AZ law, look in Washington. BTW, the above quote suggests that Russia is not a developed nation, a fair evaluation of Russian Siberia where the border with China is located.
