Summary
ISIS was created and defended by the US.
Disproof
No evidence is given. Recurring pro-Kremlin disinformation narrative claiming that the US and other Western states are supporting or working together with ISIS in the Middle East. This message is part of a broader conspiracy theory alleging that the United States and its NATO partners have created and supported many jihadi terrorist organisations and control global terrorism. In reality, the US is committed to fighting terrorist organisations, such as Daesh and Al-Qaeda.
