Well, that's quite an outpouring of sentiment, Bob! My initial redaction is this: "Get over it, Bob. Human beings are inherently racist, biased, prejudiced, partisan, irrational, emotional, sentimental, convoluted, misinformed, unfair, atavistic, illogical, inconsistent, myopic, unlinear, and...if we are good little Christian 'believers'...'imperfect' iterations of a (mythical) mystical 'higher omniscience'"
Just as 'people of color' feel kindred connections to their erstwhile lands of origin, so too do us 'evil white people' feel strong connections to our own similar sources of ancestral origins; it's an anthropological verity demonstrated exponentially, time and time again. And when 'white' Americans constitute almost two-thirds (roughly 61.6%, according to the 2020 US Census) of the population, a natural bias towards their source ethnicity is somewhat more understandable.
A preponderant portion of that 62% trace their ancestral roots to Europe, so it is therefore understandable that they might feel greater affinity for the Ukrainian people than for your poor, suffering Sudanese (for the record, I have at least a dozen confreres and personal friends who are Sudanese, hailing back to many years of work in the Middle East and they are all wonderful, exemplary and equally deserving people). There's nothing unusual or singularly odd about that.
As for Biden getting 'awkwardly' out of Afghanistan, you're being needlessly and undeservedly kind, there, Bob. Biden has about as much foreign policy sagacity as a unicellular dollop of tidal pool sea-slime (and that's being kind). More realistically speaking, Biden's shameful and sudden withdrawal from Afghanistan was nothing short of a horrific disaster and an near-unimaginable national disgrace (and that's being kind, also). It will hopefully be remembered long after his administration has come to it's well-deserved, mediocre end, as a new low in recent American political history.
Regardless of my concurrence with you that wars (of any kind) are always a tragic (and often needless) state of affairs, personally speaking my blood boils when I witness a certifiably mad, pathetic 'little man' like Putin savagely committing genocidal war-crimes against a nation simply because he wishes to cement his ambition to be the emerging 'new Tsar' of Russia. We have seen Russia revert to this type over and over throughout the past several centuries and 'Vladolf Putler' is merely the latest reincarnation. The only thing he recognizes (as your atypical 'evil person') is the same sort of blunt physical force he is currently employing over there in Ukraine, and we have been so busy 'pussy-footing' circumferentially around his egregiousness that he has able to 'play' the US like a Stradivarius violin.
So, yes, Bob: Calm down, get over your racially substrated outrage over the perceived inequities you cite in this comparision of apples and oranges and let's get on with our daily concerns. Life isn't fair, it never has been and never will be, regardless of all the hopeful idealism that underlies a common wish for it in human affairs. Let's just have a nice glass of good wine (no 'Two-Buck Chuck' will do), hug our loved ones (again) and be damn glad that, although we could very well suffer something like this in our own future, things haven't been reduced to that just yet!
I am not hopeful about the specific potentials of our species but I am at least realistic! Thanks for this dash of Angostura Bitters in my virtual AM Irish coffee, LoL! :)
