Maybe new for you, but, Usa and Israel do also sponsor or have sponsored terrorists. It is a very loose definition "state sponsor of terrorism"
So, who decides what is sponsored terrorism?
The State of Israel has been accused of engaging in state-sponsored terrorism,[1] as well as committing acts of state terrorism on a daily basis in the Palestinian territories.[2] Countries that have condemned Israel's role as a perpetrator of state-sponsored terrorism or state terrorism include Bolivia,[3] Iran, Lebanon,[4] Saudi Arabia,[5] Syria,[6] Turkey,[7] and Yemen.[8]

The United States has at various times in recent history provided support to terrorist and paramilitary organizations around the world. It has also provided assistance to numerous authoritarian regimes that have used state terrorism as a tool of repression.[1][2
