adjective
invincible
in-VIN-suh-bul/ɪnˈvɪnsəbl/
Impossible to defeat or overcome.
The intact fortress appears invincible above the shattered siege engines.

Etymology
The negative prefix reverses the idea of being conquerable: invincible means unable to be overcome. It therefore expresses more than strength—it presents defeat as impossible.
In context
One, it can bust through that bubble, that air of inevitability, that Trump, that this regime is invincible, is unstoppable, is all-powerful.
