The Wall

Seems Trump is really intent on doing this.

Is it a 'huuge' waste of money that won't work ?? I think so

Even if Trump can bully Mexico into paying for it, don't think that means it  is free for the US
e.g China will be there happily waiting to court Mexico

Do you think they can build a wall that can't be climbed ??
Walls are very expensive to cover all the terrain of the US Mexico border
Ladders/ropes are cheap

I admit I have no experience in building (what is it?) a 3000km wall
...but neither does Trump

But really?? common sense is enough to see the folly in this
