The Guardian reports:
The Republican presidential candidate Scott Walker said on Sunday that building a wall on the US northern border with Canada was “a legitimate issue for us to look at”.
Asked in an interview on NBC if he wanted to build a wall on the Canadian border, the Wisconsin governor cited his experience talking to voters “including some law enforcement folks” in New Hampshire, an early voting state in the Republican primaries. Such people, he said, were concerned about terrorists potentially crossing over from Canada.
“They raised some very legitimate concerns, including some law enforcement folks that brought that up to me at one of our town hall meetings about a week and a half ago,” Walker said. “So that is a legitimate issue for us to look at.”
So a 2000 km long wall on the southern border and one of the same size on the northern border.
But what about the east and west coast? Terrorists could come in by boat.I think they need a 100 metre high wall along both coasts.
New Zealand may have to look at this also. We have no wall preventing Australian terrorists crossing over the Tasman Sea by boat.
