First and foremost, the lira decline has been ongoing for some time, and has nothing to do with the strength of the US dollar in 2018

Those that say that "a country with monetary sovereignty can issue all the currency it wants without risk of default " are wrong yet again. Like in Argentina, Brazil, Iran, Venezuela, monetary sovereignty means nothing without strong fundamentals to back the currency.
