Extremist groups have attempted to change the meaning of freedom and liberty embedded in Patriots’ Day — a commemoration of the battles of Lexington and Concord – to serve their far-right rhetoric, recruitment, and radicalization.

Hayat Tahrir al-Sham’s background as a former branch of ISIS and al-Qa`ida has raised concerns about its trustworthiness regarding the interests of the U.S. and its allies. But the group’s record is reassuring: The largest threats to outside countries in Syria remain the Islamic State, remnant Hezbollah networks, and the criminal captagon trade.

The recent discovery of a caravan full of explosives in Dural, in Sydney’s northwest, caused significant fear about the possibility of a mass casualty attack. The Australian Federal Police declared it and 14 antisemitic attacks a “con job” by organized criminals who were trying to distract police or use it as a bargaining chip to influence prosecutions.
