Sorry Pie wall going to be part fence. This is going to get good.
Fences can work too. They worked in hungary.
He said there "could" be fences in some parts.
Honestly, I think he is just trying to not rile up the left anymore than they are. Plus he has the establishment paying people to trash his property, make death threats, spread lies through the media.
He is playing it safe. He always said, dont tell your enemy the plan. So he speaks in generalities.
The establishment would love to see an accident or assassination happen. As would half of the liberals here.
