What I am trying to make you understand is that that definition only defined what terrorists do, not who they are. To understand who they are requires you to accept the fact that by definition states aren’t terrorists when they use their military in an open and transparent fashion. So who are terrorists? Terrorists are unaffiliated with state governments. They may receive support from state governments but those governments disavow their support.
Now do you understand?
Yes. The dictionary definition of terrorism makes you squirm because it's obvious the US is guilty of it so you try to change the definition. Nothing new. As though terrorists don't act in an open fashion when they claim responsibility for their actions.
Further, states are terrorists when they use their military for terror.
