I'm glad you have an opinion on what the new administration should have done. It has nothing to do with my point, which is that if you make a list you may be pointing a gun that you can't foresee or understand.So Obama should've done nothing with foreign policy? I don't know what you're saying here. You know the whole reason they used that list (aside from it excluding Trump's business partners) was so when people complained they could pretend that Obama did the exact same thing. Nothing was stopping them from coming up with their own list of countries.
I suggest, therefore, a careful look at all the lists the previous administration made and consideration about how the current administration will abuse them.
I suggest we should generally be discouraging such lists, and only make them under exceptional circumstances and limit them as much as possible.
It's not obamas direct fault that the current administration is abusing one of his lists, but he isn't entirely blameless either.
Lists are necessarily general in nature and will sweep innocent as well as malicious into the bin.
All I'm suggesting is that we should be more careful making them in the first place.
