Its an observation and a question more than an opinion, but *perhaps* an unwillingness by certain populations to engage, discuss and consider the detail of the global implications of policy formed by these policy makers, lies at the very core of why certain individuals have ended up being given such power in the first place?
Personally I feel that not discussing the power-brokers policy means it becomes impossible to have an intelligent conversation about the subject when, as you point out, US policy will be the ultimate decider of the fate of Ukraine. Its indivisible. As is its global impact.
What we all know is really meant, given expressing views and opinions about anyone else doesn't seem to result in 'out of control conversations', is not expressing an opinion on Trump and his administration. It'll be interesting to see what passes that test for 'discussion' here, post 20th of January!
