A Saudi lobby in DC maintains that the real worry is about the security of the regime and not about terrorism

Wait. I thought that they are worried about the spread of terrorism but here it talks about threats to regimes: "Saudi and the UAE will also demand that Qatar reign in Al-Jazeera which consistently propagates Islamist-inspired propaganda that undermines their regimes."  Also, if Aljazeera is Islamist-oriented (which it has become since at least 2010), what does that make Saudi Arabia? A staunch secular regime?
