If they wanted to be associated with Al-queda they could have done that a long time ago when they were asked to fight in Iraq along with them , which they declined. I doubt they will involve themselves with it. More attempts at villification through association. Israel is trying hard to see american blood spill in their mess.
What could this idiot bring to the table? Unless he's giving them some weapons they don't seem to need his help.

They didn't join them in Iraq because they don't fight their own wars - they do it via proxy, as we have found out with Hezbollah.

Last week, al-Zawahri called for muslims everywhere to join in the Lebanese conflict against the Israelis. Using Saad is part of that, to encourage al Qaeda members to become Iranian proxies.
