You aren't troubled by a foreign government urging it's citizens to break laws in the USA?

That's just it, I didn't get the impression that they were urging people to cross the border. To urge them would have been to portray the US as the land of milk and honey. All this pamphlet did was tell them how not to get lost in the desert and to avoid coyotes. It also told them that they should try coming here legally first.
