Migration is definately going on all over the world. Fortunately, we are producing reverse migration in Afghanistan and Iraq.
No we're not. I don't know anybody who is planning to leave the US and go live in either country. We've got some military troops on the ground, but that's hardly a "migration." The natives are still in control in both countries.
Not in Mexico. They kick you out if you cross their border illegally. In contrast, George Bush has said, through his policies about immigrants, bring em on! So migration is happening in US, but not "all over the world."
