Will attack in Qatar lead to international isolation of Israel?

What we see right now ... is one party to the negotiations is trying to assassinate the other party in the negotiations on the territory of the mediator country ... [it will] raise questions around the security guarantees that they [Qatar] thought that they had from the United States. I think that they will be wondering if those actually still hold. It won't be simply the Qataris who will be asking those questions but others in the Gulf among American allies and wider in the region itself."
