Re: About this new wall
It's pretty much irrelevant, as drugs are not flowing through the places where the wall would be built. In fact, neither are illegal immigrants.
The whole thing is largely symbolic. The money Trump asked wouldn't be enough to build the wall in the first place; but it would allow him to claim victory. It would allow him to claim the wall has been built (even if incomplete, useless and unmaintainable). That's why it's so important to Trump. And that's also why the Democrats are opposing it so much, even though when you come to it, it's a relatively small amount of money.
The UK politics are in a crisis right now, but at least the stakes are huge. It's pretty much the most important decision the country will take for decades. In comparison, the US is fighting over who gets to sit by the window.
