What is terrorism?

This is part of a poem about Palestine that I was reading online (the part I liked the best)

“I’ve known terrorism for quite some time,
Fifty-five years and more.
It’s the fruitless garden uprooted in my yard.
It’s the bulldozer in front of my door.

Terrorism breathes the air I breathe.
It’s the checkpoint on my way to school.
It’s the curfew that jails me in my own home,
And the penalties of breaking that curfew rule.

Terrorism is the robbery of my land,
And the torture of my mother,
The imprisonment of my innocent father,
The bullet in my baby brother.”
