"because in fact NOBODY is saying that it is"
They are sure acting like it is and there have been frequent references in the comments here to 1933 Germany - in fact there is one by Ron McAllister just two comments below yours. So it is in fact a pretty reasonable comment for her to make.
As for the 7 countries chosen they are apparently from a list of problem countries drawn up during the Obama administration. So best to criticise Obama for that.
"When people are stating that they have no idea what the President will do"
No, people making statements about someone being unpredictable is not a sign of mental illness in that person. Do you not have even the slightest bit of shame in saying something like that? 
As for predictability Trump said in his campaign he would do these things so, whether you find them good or bad,  if you find them surprising you weren't paying attention.
