Hamas isn't the only terror group that the PLO wants to unify with

From Ma'an:

A delegation of independent political figures met with members of the Islamic Jihad Movement in the Gaza Strip on Thursday to continue reconciliation talks among Palestinian factions.
The delegation was headed by Yasser al-Wadiya, member of the Palestinian Liberation Organization (PLO) leadership, who updated Islamic Jihad's leaders on the results of his latest visit to Egypt to work on the ongoing process of national reconciliation.

The PLO executive committee appointed a committee to consult all Palestinian factions on reforming a new government in mid-June, and it was widely expected that the new government would see factional leaders replace the current government's independent technocrats.

Islamic Jihad and Hamas are not PLO members but are allegedly included in talks.

There are plenty of people throughout the years that have tried to rehabilitate Hamas' image, claiming that it now runs a (shadow) government and it is more practical and pragmatic and not solely fixated on terror, despite daily statements calling for genocide against Jewish Israelis.

But Islamic Jihad cannot be considered anything but a terror group. And the "moderate" PLO is considering them as legitimate as any other political party.

Which tells you all you need to know about the PLO. Too bad the rest of the world closes its eyes to that small fact.
