Research tells us that vehicle ramming became the most lethal terrorist attack method in 2016; the too-softly-named “Counter Extremism Project” published a report this year that documented 83 such attacks that resulted in 261 deaths and close to 1,500 injuries. Between 1970 and 2019, there were just over 800 fatalities and 1,800 injuries from 257 such attacks. In their twisted minds, a strategy that works is something worth doing again.
