“These are foreigners, not Americans. This is a terrorist attack.”
This is an act of war, since they are foreigners. There really isn’t anything called a “terrorist attack”. That’s just what the elites want you to call it so that you do not go to war.
War is between at least two state entities or defined parties. These foreigners are acting independently of their governments. Many of them are Antifa.
Terrorism is one description under the Military Operations Other Than War (MOOTWa) umbrella.
