There are no problems with the Al-Thani dynasty who originates from KSA like practically every native Qatari. What is the "problem" here are CERTAIN policies of the past dethroned Emir (Sheikh Hamad) that his son has continued.
You have to have in mind that Sheikh Hamad removed his own father from the throne back in 1995 and in 2013 (after the Gaddafi-Hamad scandal erupted) Hamad was forced to step down and his son Tamim took the throne. So they are good at removing themselves which is quite unprecedented in the GCC outside of the current Omani Sultan who has ruled since 1970, who removed his father as well.
Qatar is a paper tiger. They can't accomplish anything on their own. Their biggest asset is Al-Jazeera, while once very popular, has lost most of its viewers lately. Such a tiny state will not be allowed to disrupt the GCC which I doubt that they want to do but certain of their policies that are counterproductive (viewed by most GCC and Arab countries) will not continue. Not in the current geopolitical situation in the region which is volatile for everyone involved.
That is what can happen, as I explained in post 186 or was it 187 (don't remember) if a mouse things that he is a lion and when it gets delusions of grandeur.
In that clip (pre-2011), Gaddafi and Sheikh Hamad were talking about how to destroy KSA. One is dead (Gaddafi) with his regime gone for good and another was dethroned due to this exact statement which became leaked in 2013. Sheikh Tamim will face the same fate if his policies do not change. Nobody will protect him.
