The idea that Abbas will cancel the unity pact over this is pie in the sky. It assumes that muslim terrorists are sane.
No his hurried meeting is more likely how to parlay this into increased EU funds for the PA. Its a meeting of rats, not men.
The unity pact fell apart once before. And there’s a lot of bad blood between them, considering that Hamas took away Gaza from the Palestinian Authority and murdered a lot of their people. I think the Palestinian Authority is just looking for an excuse to dump Hamas.
