thats PPP not GDP
but he is right Turkish GDP is too small for its size
GDP PPP for human development index
because adjusted for the cost living in each Country.
GDP PPP shows measure of a country's average achievements in dimensions of human development
-- standard of living, as measured by GNI per capita in PPP terms in USD ($)
and Turkiye has $3,5 trillion of GDP PPP
btw Turkiye had $960 billion of GDP Nominal even in 2013
but since 2013 , Turkiye and Turkish economy under attack led by USA
also Turkiye lost $1 trillion to fight USA-The EU backed PKK terrorism since 1985
1 USD has risen to 1.8 TL from 1.3 TL between 2003 and 2013
1 USD has risen to 26 TL from 1.8 TL between 2013 and 2023
Turkish currency droped by 1.440% between 2013 and 2023
if there were no attacks on Turkiye and Turkish economy since 2013 , now Turkiye would have min $2,5 trillion of GDP Nominal instead of $1 trillion
the Netherlands so lucky because nobody attacks the Netherlands and use EURO ( currency )
