There are several explanations offered for Egypt, Saudi Arabia, Bahrain, & the UAE severing diplomatic ties & expelling Qatar from the coalition bombing Yemen to smithereens. None of the reasons are persuasive & in all of them someone is lying because the story doesn’t add up. The one about ransoming the kidnapped royal hunting party in Iraq takes the cake.
The most compelling one might be Qatar support for Palestinians if it can be proven that the country has actually given substantial aid or any aid at all other than asylum to a Hamas official.
This is another case where experts emerge from the woodwork even though they had to look up the location of Qatar before they began speculating. Facts have to emerge before there can be any understanding of what this is all about. But any breakdown in that Yemen war coalition has to be a good thing.
