My
projections tend to be logical and correct on average. Not boasting; just saying.
Saudi Arabia can invade and occupy Qatar in a span of few days, if it wants to (refer to the case of Bahrain in 2011). However, US
prevented Saudi invasion of Qatar in 2015.
Turkey have also dispatched its forces to Qatar in order to deter Saudi invasion but this contingent is only 3000 strong.
Turkey is also experiencing an economic crisis at present, and Qatar have offered 15 billion USD bailout package to Turkey recently.
Trump administration might oppose this move since US - Turkish relations are not good.
Qatar ran of favor with its GCC partners in 2015. Should it also loose support of US, it will collapse. Read this:

Saudi warning is loud and clear. Should US abandon Qatar to its fate, Saudi Arabia will execute "regime change" in Qatar. Saudi do not fear Turkey.
