Use the Stata Program -mif2dta- to produce the boundary dta File.
To produce the nonsens master file simply proceed as follows
. set obs <number>
where <number> is the number of polygons in the boundary file.
. gen id = _n
This makes the idenitier variable which correspond to the _ID variable in the
. gen xyz = uniform()
This makes an arbitrary quantitative variable to be drawn in the map.
. tmap choropleth xyz, id(id) map(boundary-file)
This produces the arbitrary non-sense map ...

No. We just tried it out and decided not to follow this path. Mainly because
the boundary file did not contain Turkey. We did not kept a copy of it.

I don't know.
