That is where you are mistaken.

First, who are domestic terrorists? BLM for certain. Antifa for certain. Both though seem to escape that recognition with the current administration. To this point, it has been up to the states in conjunction with local governments to control these groups, and many have failed miserably.

On the other hand, international terror groups were for the most part relatively quiet for the last three years of the Trump administration.

The point of this, is that is seems as though that "quiet" period is over with Bidenus Pervetus in the oval office.
