The rise of ISIS and the collapse of the Kurdish peace process had led to a sharp rise in terror incidents in Turkey until 2016. Erdoğan was accused by his critics of having a 'soft corner' for ISIS.[233] However, after the attempted coup, Erdoğan ordered the Turkish military into Syria to combat ISIS and Kurdish militant groups.[234] Erdoğan's critics have decried purges in the education system and judiciary as undermining the rule of law[235] however Erdoğan supporters argue this is a necessary measure as Gulen-linked schools cheated on entrance exams, requiring a purge in the education system and of the Gulen followers who then entered the judiciary.[236][237]
