This is where it would be.

(dog squeals)

It would have to stretch over 2,000 miles of rough terrain...

cutting through mountains,

rivers, villages

and even people's homes.

And all that destruction is monstrously expensive.

Just building the wall

would cost between $15 and $25 billion.

(woman gasps)

It would easily be one of the single most expensive pieces of infrastructure in American history

costing as much as 20 Hoover Dams

or NASA's entire annual budget.

(man) That's one small step for man,

one giant wall for no reason.

Not to mention the astronomical cost of staffing and maintaining the wall,

which taxpayers like you and your children will be stuck paying forever.

I paid for the wall.

My father's father paid for the wall.

And one day you will pay for the wall.

Because this is Wall World.

Even just faking the wall for our show was prohibitively expensive.

Looks like our CGI budget ran out.

Okay, yes, it may be expensive

but that doesn't change the fact that once we build it, it will work.

Not like you think.

Increasing security at the border

will never stop illegal immigration.

Why not?

No one's getting passed me.

Yes, they are. Because it's estimated that

between 27% and 40% of all undocumented immigrants in America came here on planes.

(plane passing)

I forgot about planes.

These immigrants didn't sneak over the border.

They came here legally,

through passport control

then just overstayed their visas.

and guess what,

the border wall's not going to stop them cause, reminder: PLANES CAN FLY OVER WALLS！
