My country is for me,
no one else can come
quoths the  American president.

I will construct a wall
allow not any Mexican enter
cries the U.S leader.

I have suspended seven country nationals.
They cannot enter the U.S territory,
dictates the newly elected leader.

What is this called?
I try to find the exact word.
an antonym for Globalisation.

it is hard to seek.
Could it be regionalisation?
narrower still- internalization.

It is shrinking.
The closing of doors and windows,
allows not the wind to enter.
