The left uses those terrorists for combat actions against countries all over the world including attacks on military targets. The are like a kind of specialized light infantry. Suicide fanatics on battle drugs. Very dangerous. Able to attack hardened targets, like prisons. Able to overcome standard second line infantry. Able to disrupt and deny transportation routes, and paralyze defense forces to keep them pinned. Very useful for overthrowing governments. No doubt they have plans for their aggressive use in the United States. Such forces can also carry out massacres against civilian populations, which normal forces are hesitant to participate in. Trump is making it harder to move them around the map. Notice how they move antifa forces around the map too. Antifa, however, are not designed for terrorism. Antifa are agitators, provocateurs, and occasionally saboteurs, but not trained for combat, when operating as a group. Yes, the left has big plans for their terror buddies. That's why they are so pissed at these new rules.
