Although the West's history (and indeed, this is applicable to any other region of the world) does indeed include skeletons in its closet, to draw a similarity between it and ISIS is an outrageous, extreme and ungrounded accusation aimed to discredit the West. See similar cases here, including claims that the West is a terrorist structure, the West is fascist, and that the US and EU countries support Russophobic, neofascist, terrorist political parties and movements in the post-Soviet space.
ISIS is a Salafi jihadist militant group and former unrecognised proto-state that follows a fundamentalist, Salafi doctrine of Sunni Islam. In 2015-2017, ISIS claimed responsibility for a number of terrorist attacks outside Iraq in Syria, including in Tunisia, Turkey, Belgium, France, Germany, Russia and other countries. ISIL has been classified a terrorist organisation by the United Nations, the European Union and its member states, the United States, Russia, India, Turkey and many other countries.
