If the fight against IS was not enough, Turkey is struggling domestically with a fractious political environment and lack of government after inconclusive elections in May. Although coalition talks are continuing, the possibility of new, early elections is still high.
Turkey's involvement in the battle against IS could make the country vulnerable – both from within and without.
For example, the PKK has already launched a series of attacks in Turkey after Friday's raids – meaning the end of a fragile ceasefire between the two sides since 2013.
Analysts agree that Turkey has suddenly become far more vulnerable to further attacks.
"Turkey's sudden decision to take the fight to Isis will likely lead to significant successful Isis attacks within Turkey, the biggest shift in terrorist vulnerability for a major emerging market since the beginning of the Arab Spring," Eurasia Group's Bremmer said.

"That in turn will put a damper on investor sentiment for the country, and make the political process in Turkey that much more challenging."
That view was echoed by Wolfango Piccoli, managing director of risk consultancy Teneo Intelligence, who said in a note on Monday that civil unrest in Turkey was likely to rise.
"Ankara's recent adoption of aggressive policies towards both the Kurdish Workers' Party (PKK) and the Islamic State (IS) has considerably raised the risk of terrorist attacks and sustained civil unrest inside the country," Piccoli warned.
"Amid continued speculation that the ruling Justice and Development Party (AKP) may call an early election for November 2015, there appears little prospect of the country enjoying political stability in the foreseeable future."
