1. orathaic and I, we're not the same person.
2. I referred to a fantasy story, but I don't think Trump's wall is not any less fantastic than Westeros' wall.
3. My logic goes as follow. If you just keep trimming the twigs of the tree, but keep letting water and sun to nurish the tree, you'll never get rid of the tree. Want to solve illegal migration? try to find the root of the problem.
There's a difference between thiefs and illicit drugs, for the illicit drugs there are both, sellers and buyers, and both parts get what they want, it's a mutual deal based on agreement. Instead, no one agrees to be stolen.
The problem is not that laboral situation is bad in Mexico, and even worse in other central american countries. The problem is that, in many cases, there's no laboral situation at all, all there is is violence and misery. So, people will keep flowing massively. They don't mind to be killed by mexican mafias that extort them brutally, or by the already brutal border patrol; there won't be wall nor border patrol brutality to stop them, cos they come from the very hell. And as long as there are gringos ready to hire them, they'll keep seing US as the only way out of hell.
I don't say that you'd do bad reinforcing security, what I say is, that unless you pretend to invade Mexico and establish apartheids worse than Nazi ghettos (probably that's what you'd really like), no security measure will be anough, ALONE, to solve the problem.
