What possible “detrimental consequences later on” do you fantasize about?
Ukraine is a former Soviet state, just like Russia, not a member of NATO, besides being the epicenter of corruption. Who cares, let them squabbling. Ask yourself why we did nothing (other than a sternly worded letter) when Russia annexed Crimea 9 years ago. Ask yourself why we don’t get involved in any of the half dozen wars ongoing worldwide right now. What makes Ukraine so special this time around and why?
The detrimental consequences we have NOW because of our involvement is the debasement of our currency, de-dollarization of the world reserve currency, strengthening and expansion of the BRICs alliance, not to mention the loss of diplomatic clout in the Mid-East, Africa, and South America.
