It's the worst dispute to hit this region since the founding of the Gulf Cooperation Council in 1981.

Now, a little more than a month into a blockade of Qatar imposed by Saudi Arabia, Bahrain, the United Arab Emirates and Egypt; the United States is taking an active diplomatic approach.

Secretary of State Rex Tillerson is visiting Saudi Arabia - after having made stops in Doha and Kuwait City over the last few days.

He praised Qatar after it became the first regional power to sign a memorandum of understanding with the US to fight "terror" financing.

But can he change the positions of the blockading countries?
